New American Standard Bible (NASB)
Exodus 19
21 Then the Lord spoke to Moses, "Go down, warn the people, so that they do not break through to the Lord to gaze, and many of them perish.
22 Also let the priests who come near to the Lord consecrate themselves, or else the Lord will break out against them."
23 Moses said to the Lord, "The people cannot come up to Mount Sinai, for You warned us, saying, ’Set bounds about the mountain and consecrate it.’"
24 Then the Lord said to him, "Go down and come up again, you and Aaron with you; but do not let the priests and the people break through to come up to the Lord, or He will break forth upon them."
25 So Moses went down to the people and told them.
Exodus 20
1 Then God spoke all these words, saying,
2 "I am the Lord your God, who brought you out of the land of Egypt, out of the house of slavery.
3 "You shall have no other gods before Me.
4 "You shall not make for yourself an idol, or any likeness of what is in heaven above or on the earth beneath or in the water under the earth.
5 You shall not worship them or serve them; for I, the Lord your God, am a jealous God, visiting the iniquity of the fathers on the children, on the third and the fourth generations of those who hate Me,
6 but showing lovingkindness to thousands, to those who love Me and keep My commandments.
