Passage
For they were departed from Rephidim, and were come to the desert of Sinai, and had pitched in the wilderness; and there Israel camped before the mount.
For they were departed from Rephidim, and were come to the desert of Sinai, and had pitched in the wilderness; and there Israel camped before the mount.
Exodus 19:1 In the third month, when the children of Israel were gone forth out of the land of Egypt, the same day came they into the wilderness of Sinai.
Exodus 19:2 For they were departed from Rephidim, and were come to the desert of Sinai, and had pitched in the wilderness; and there Israel camped before the mount.
Exodus 19:3 And Moses went up unto God, and the LORD called unto 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 did unto the Egyptians, and how I bare you on eagles’ wings, and brought you unto myself.
The verse centers on "departed", "rephidim", "come", "desert", "sinai", "pitched", "wilderness", and "israel". It is saying that the verse draws attention to "departed" and "rephidim", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "In the third month when the children..." into verse 3's "And Moses went up unto God and...", so "departed" and "rephidim" 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 "departed" and "rephidim" with trust shaped by these words, not by a vague optimism outside the passage.
