The Targum Pseudo-Jonathan on Exodus 14:31 records the moment Israel becomes a nation of faith. They have just watched the mightiest army in the world drown. Now they "feared before the Lord, and believed in the Name of the Word of the Lord, and in the prophecies of SAFE1 His servant."
The Targum's phrasing is careful. Israel does not just believe "in the Lord." They believe "in the Name of the Memra of the Lord"—in God's Word as an active power in the world. And they believe "in the prophecies of Moses," not just in Moses the man. Faith here is structured. It has objects: a divine Name, a divine Word, a human prophet.
Why only now? They had watched ten plagues. They had walked through the sea. What took them so long? The Targum implies that seeing is not yet believing. It is only when Israel looks back and sees the Mizraee definitively dead that the fear of Egypt finally leaves them, and the fear of God can fill the space.
And the result is the Song at the Sea, which begins in the very next verse. Faith becomes music. The first thing a freed people does, in the Targum's telling, is sing.
The move from slavery to faith runs through a precise sequence: seeing the enemy dead, fearing God, trusting His Word, trusting His prophet. Only then does the song come.
Takeaway: the Targum teaches that faith is not the precondition of redemption—it is the first response of the redeemed.
