19 So on the tenth day of the first month the people came up out of Jordan, and put up their tents in Gilgal, on the east side of Jericho.

20 And the twelve stones which they took out of Jordan, Joshua put up in Gilgal. 21 And he said to the children of Israel, When your children say to their fathers in time to come, What is the reason for these stones? 22 Then give your children the story, and say, Israel came over this river Jordan on dry land. 23 For the Lord your God made the waters of Jordan dry before you till you had gone across, as he did to the Red Sea, drying it up before us till we had gone across: 24 So that all the peoples of the earth may see that the hand of the Lord is strong; and that they may go in fear of the Lord your God for ever.

Matthew Henry's Commentary on Joshua 4:19-24

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!
