This is a polite way of referring to a man's private parts. See how you translated a similar phrase in [Leviticus 15:1](../15/01.md). Alternate translation: "from his private parts" (See: [[rc://en/ta/man/jit/figs-euphemism]])
This can be stated in active form. Alternate translation: "the sacrifices that someone has offered to Yahweh" (See: [[rc://en/ta/man/jit/figs-activepassive]])
