19 The people crossed the Jordan on the tenth day of the first month. Then they camped at Gilgal, just east of Jericho.

20 It was there at Gilgal that Joshua piled up the twelve stones taken from the Jordan River. 21 Then Joshua said to the Israelites, "In the future your children will ask, 'What do these stones mean?' 22 Then you can tell them, 'This is where the Israelites crossed the Jordan on dry ground.' 23 For the Lord your God dried up the river right before your eyes, and he kept it dry until you were all across, just as he did at the Red Sea when he dried it up until we had all crossed over. 24 He did this so all the nations of the earth might know that the Lord 's hand is powerful, and so you might fear the Lord your God forever."

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!
