Passage
And Moses went down from the mount unto the people, and sanctified the people; and they washed their clothes.
And Moses went down from the mount unto the people, and sanctified the people; and they washed their clothes.
Exodus 19:12 And thou shalt set bounds unto the people round about, saying, Take heed to yourselves, that ye go not up into the mount, or touch the border of it: whosoever toucheth the mount shall be surely put to death:
Exodus 19:13 There shall not an hand touch it, but he shall surely be stoned, or shot through; whether it be beast or man, it shall not live: when the trumpet soundeth long, they shall come up to the mount.
Exodus 19:14 And Moses went down from the mount unto the people, and sanctified the people; and they washed their clothes.
Exodus 19:15 And he said unto the people, Be ready against the third day: come not at your wives.
Exodus 19:16 And it came to pass on the third day in the morning, that there were thunders and lightnings, and a thick cloud upon the mount, and the voice of the trumpet exceeding loud; so that all the people that was in the camp trembled.
The verse centers on "moses", "went", "down", "mount", "people", "sanctified", and "washed". It is saying that the verse draws attention to "moses" and "went", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "There shall not an hand touch it..." into verse 15's "And he said unto the people Be...", so "moses" and "went" belong inside that flow. In Exodus context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "moses" and "went" with trust shaped by these words, not by a vague optimism outside the passage.
