Exodus 19 (Listen)

Israel at Mount Sinai

19:1 On the third new moon after the people of Israel had gone out of the land of Egypt, on that day they came into the wilderness of Sinai. 2 They set out from Rephidim and came into the wilderness of Sinai, and they encamped in the wilderness. There Israel encamped before the mountain, 3 while Moses went up to God. The LORD called to him out of the mountain, saying, “Thus you shall say to the house of Jacob, and tell the people of Israel: 4 ‘You yourselves have seen what I did to the Egyptians, and how I bore you on eagles’ wings and brought you to myself. 5 Now therefore, if you will indeed obey my voice and keep my covenant, you shall be my treasured possession among all peoples, for all the earth is mine; 6 and you shall be to me a kingdom of priests and a holy nation.’ These are the words that you shall speak to the people of Israel.”

7 So Moses came and called the elders of the people and set before them all these words that the LORD had commanded him. 8 All the people answered together and said, “All that the LORD has spoken we will do.” And Moses reported the words of the people to the LORD. 9 And the LORD said to Moses, “Behold, I am coming to you in a thick cloud, that the people may hear when I speak with you, and may also believe you forever.”

When Moses told the words of the people to the LORD, 10 the LORD said to Moses, “Go to the people and consecrate them today and tomorrow, and let them wash their garments 11 and be ready for the third day. For on the third day the LORD will come down on Mount Sinai in the sight of all the people. 12 And you shall set limits for the people all around, saying, ‘Take care not to go up into the mountain or touch the edge of it. Whoever touches the mountain shall be put to death. 13 No hand shall touch him, but he shall be stoned or shot;¹ whether beast or man, he shall not live.’ When the trumpet sounds a long blast, they shall come up to the mountain.” 14 So Moses went down from the mountain to the people and consecrated the people; and they washed their garments. 15 And he said to the people, “Be ready for the third day; do not go near a woman.”

16 On the morning of the third day there were thunders and lightnings and a thick cloud on the mountain and a very loud trumpet blast, so that all the people in the camp trembled. 17 Then Moses brought the people out of the camp to meet God, and they took their stand at the foot of the mountain. 18 Now Mount Sinai was wrapped in smoke because the LORD had descended on it in fire. The smoke of it went up like the smoke of a kiln, and the whole mountain trembled greatly. 19 And as the sound of the trumpet grew louder and louder, Moses spoke, and God answered him in thunder. 20 The LORD came down on Mount Sinai, to the top of the mountain. And the LORD called Moses to the top of the mountain, and Moses went up.

21 And the LORD said to Moses, “Go down and warn the people, lest they break through to the LORD to look and many of them perish. 22 Also let the priests who come near to the LORD consecrate themselves, lest the LORD break out against them.” 23 And Moses said to the LORD, “The people cannot come up to Mount Sinai, for you yourself warned us, saying, ‘Set limits around the mountain and consecrate it.’” 24 And the LORD said to him, “Go down, and come up bringing Aaron with you. But do not let the priests and the people break through to come up to the LORD, lest he break out against them.” 25 So Moses went down to the people and told them.

From bondage, to deliverance, and now to the organization of God's nation. He began by reminding His children how powerfully He'd protected & nurtured them, bringing them to Himself. If they would but obey His Word & keep His covenant they'd be His "treasured possession among all peoples, for all the earth is" His.
"Oh, is that all? No problem," they quickly replied. But from this point on the tone of the Most High changed significantly, speaking through thunder & descending smoke; His holiness caused great trembling. "Warn the people," He instructed Moses.
Still today God's children must keep perspective on God's purity & power to remain faithful in His covenant.

Acts 19:1–22 (Listen)

Paul in Ephesus

19:1 And it happened that while Apollos was at Corinth, Paul passed through the inland¹ country and came to Ephesus. There he found some disciples. 2 And he said to them, “Did you receive the Holy Spirit when you believed?” And they said, “No, we have not even heard that there is a Holy Spirit.” 3 And he said, “Into what then were you baptized?” They said, “Into John’s baptism.” 4 And Paul said, “John baptized with the baptism of repentance, telling the people to believe in the one who was to come after him, that is, Jesus.” 5 On hearing this, they were baptized in² the name of the Lord Jesus. 6 And when Paul had laid his hands on them, the Holy Spirit came on them, and they began speaking in tongues and prophesying. 7 There were about twelve men in all.

8 And he entered the synagogue and for three months spoke boldly, reasoning and persuading them about the kingdom of God. 9 But when some became stubborn and continued in unbelief, speaking evil of the Way before the congregation, he withdrew from them and took the disciples with him, reasoning daily in the hall of Tyrannus.³ 10 This continued for two years, so that all the residents of Asia heard the word of the Lord, both Jews and Greeks.

The Sons of Sceva

11 And God was doing extraordinary miracles by the hands of Paul, 12 so that even handkerchiefs or aprons that had touched his skin were carried away to the sick, and their diseases left them and the evil spirits came out of them. 13 Then some of the itinerant Jewish exorcists undertook to invoke the name of the Lord Jesus over those who had evil spirits, saying, “I adjure you by the Jesus whom Paul proclaims.” 14 Seven sons of a Jewish high priest named Sceva were doing this. 15 But the evil spirit answered them, “Jesus I know, and Paul I recognize, but who are you?” 16 And the man in whom was the evil spirit leaped on them, mastered all⁴ of them and overpowered them, so that they fled out of that house naked and wounded. 17 And this became known to all the residents of Ephesus, both Jews and Greeks. And fear fell upon them all, and the name of the Lord Jesus was extolled. 18 Also many of those who were now believers came, confessing and divulging their practices. 19 And a number of those who had practiced magic arts brought their books together and burned them in the sight of all. And they counted the value of them and found it came to fifty thousand pieces of silver. 20 So the word of the Lord continued to increase and prevail mightily.

A Riot at Ephesus

21 Now after these events Paul resolved in the Spirit to pass through Macedonia and Achaia and go to Jerusalem, saying, “After I have been there, I must also see Rome.” 22 And having sent into Macedonia two of his helpers, Timothy and Erastus, he himself stayed in Asia for a while.

(ESV)

The diligent work of Apollos met with Paul's proclamation of the risen Christ and about 12 disciples received the manifestation of the Spirit as Paul laid hands on them.
After three months of effort in the synagogue, Paul spent the remainder of two years sharing the Good News of Jesus' death & resurrection "so that all residents of Asia heard..."
God endorsed Paul's frontier efforts by granting extraordinary miracles, meriting an audience in Asia, including intenerant Jewish exorcists who left naked & wounded having tried to leverage "Paul's power" without knowing its source. Fear fell upon all & the name of Jesus prevailed mightily.
