tn The substantive כֹּל (kol) followed by the article stresses the entirety—“all sons” or “all daughters”—even though the nouns are singular in Hebrew (see GKC 411 §127.b).

tn The form includes a pronominal suffix that reiterates the object of the verb: “every son … you will throw it.”

tn The first imperfect has the force of a definite order, but the second, concerning the girls, could also have the nuance of permission, which may fit better. Pharaoh is simply allowing the girls to live.

sn Verse 22 forms a fitting climax to the chapter, in which the king continually seeks to destroy the Israelite strength. Finally, with this decree, he throws off any subtlety and commands the open extermination of Hebrew males. The verse forms a transition to the next chapter, in which Moses is saved by Pharaoh’s own daughter. These chapters show that the king’s efforts to destroy the strength of Israel—so clearly a work of God—met with failure again and again. And that failure involved the efforts of women, whom Pharaoh did not consider a threat.
