And his sister stood afar off, to wit what would be done to him.

Jamieson-Fausset-Brown Bible Commentary

4. his sister-Miriam would probably be a girl of ten or twelve years of age at the time.

Matthew Henry's Concise Commentary

2:1-4 Observe the order of Providence: just at the time when Pharaoh's cruelty rose to its height by ordering the Hebrew children to be drowned, the deliverer was born. When men are contriving the ruin of the church, God is preparing for its salvation. The parents of Moses saw he was a goodly child. A lively faith can take encouragement from the least hint of the Divine favour. It is said, Heb 11:23, that the parents of Moses hid him by faith; they had the promise that Israel should be preserved, which they relied upon. Faith in God's promise quickens to the use of lawful means for obtaining mercy. Duty is ours, events are God's. Faith in God will set us above the fear of man. At three months' end, when they could not hide the infant any longer, they put him in an ark of bulrushes by the river's brink, and set his sister to watch. And if the weak affection of a mother were thus careful, what shall we think of Him, whose love, whose compassion is, as himself, boundless. Moses never had a stronger protection about him, no, not when all the Israelites were round his tent in the wilderness, than now, when he lay alone, a helpless babe upon the waves. No water, no Egyptian can hurt him. When we seem most neglected and forlorn, God is most present with us.
