"as surely as Yahweh, the one who made us, is alive." This is a way of making a solemn promise. The king says it to emphasize that what he is about to say next is true. See how you translated "As Yahweh lives" in [Jeremiah 4:2](../04/02.md). Alternate translation: "I solemnly swear by Yahweh, the one who made us" (See: [[rc://en/ta/man/jit/figs-idiom]])
Here the word "hand" refers to the men's control or power. Alternate translation: "I will not ... allow those men to capture you" (See: [[rc://en/ta/man/jit/figs-metonymy]])
This phrase represents wanting or trying to kill someone. See how this phrase is translated in [Jeremiah 11:21](../11/21.md). Alternate translation: "trying to kill you" (See: [[rc://en/ta/man/jit/figs-metaphor]])
