Passage
And Moses went up to God, and Jehovah called to him out of the mountain, saying, Thus shalt thou say to the house of Jacob, and tell the children of Israel:
And Moses went up to God, and Jehovah called to him out of the mountain, saying, Thus shalt thou say to the house of Jacob, and tell the children of Israel:
Exodus 19:1 In the third month after the departure of the children of Israel out of the land of Egypt, the same day came they [into] the wilderness of Sinai:
Exodus 19:2 they departed from Rephidim, and came [into] the wilderness of Sinai, and encamped in the wilderness; and Israel encamped there before the mountain.
Exodus 19:3 And Moses went up to God, and Jehovah called to him out of the mountain, saying, Thus shalt thou say to the house of Jacob, and tell the children of Israel:
Exodus 19:4 Ye have seen what I have done to the Egyptians, and [how] I have borne you on eagles' wings and brought you to myself.
Exodus 19:5 And now, if ye will hearken to my voice indeed and keep my covenant, then shall ye be my own possession out of all the peoples for all the earth is mine
The verse centers on "called", "moses", "went", "jehovah", "mountain", "saying", "thus", and "shalt". It is saying that the verse draws attention to "called" and "moses", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 2's "they departed from Rephidim and came into..." into verse 4's "Ye have seen what I have done...", so "called" and "moses" 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 "called" and "moses" with trust shaped by these words, not by a vague optimism outside the passage.
