19 The people came up out of the Jordan on the tenth day of the first month. They set up camp at The Gilgal (The Circle) to the east of Jericho.

20 Joshua erected a monument at The Gilgal, using the twelve stones that they had taken from the Jordan. 21 And then he told the People of Israel, "In the days to come, when your children ask their fathers, 'What are these stones doing here?' 22 tell your children this: 'Israel crossed over this Jordan on dry ground.' 23 "Yes, God, your God, dried up the Jordan's waters for you until you had crossed, just as God, your God, did at the Red Sea, which had dried up before us until we had crossed. 24 This was so that everybody on earth would recognize how strong God's rescuing hand is and so that you would hold God in solemn reverence always."

Commentary on Joshua 4:10-19

(Read Joshua 4:10-19)

The priests with the ark did not stir till ordered to move. Let none be weary of waiting, while they have the tokens of God's presence with them, even the ark of the covenant, though it be in the depths of adversity. Notice is taken of the honour put upon Joshua. Those are feared in the best manner, and to the best purpose, who make it appear that God is with them, and that they set him before them.

Commentary on Joshua 4:20-24

(Read Joshua 4:20-24)

It is the duty of parents to tell their children betimes of the words and works of God, that they may be trained up in the way they should go. In all the instruction parents give their children, they should teach them to fear God. Serious godliness is the best learning. Are we not called, as much as the Israelites, to praise the loving-kindness of our God? Shall we not raise a pillar to our God, who has brought us through dangers and distresses in so wonderful a way? For hitherto the Lord hath helped us, as much as he did his saints of old. How great the stupidity and ingratitude of men, who perceive not His hand, and will not acknowledge his goodness, in their frequent deliverances!
