Deuteronomy 10:3 Meaning and Commentary

Deuteronomy 10:3

And I made an ark of shittim wood
That is, ordered it to be made, and it was made by Bezaleel, and that of shittim wood: so the ark that was put into the holy of holies was made of this wood; see (See Gill on Exodus 25:10), (See Gill on Exodus 37:1),

and hewed two tables of stone like unto the first;
two marble ones, as the Targum of Jonathan; that is, he ordered them to be hewed, and took care that they should be exactly made as the former were, of which he had perfect knowledge, having received them of the Lord, and brought them with him down the mount:

and went up into the mount, having the two tables in my hand;
in order to have the words of the law, the ten commands, written on them, these being only hewn stones, without anything on them: they were very probably marble, of which great quantities were near at hand.

Deuteronomy 10:3 In-Context

1 At that time the Lord said to me, Hew for thyself two stone tables as the first, and come up to me into the mountain, and thou shalt make for thyself an ark of wood.
2 And thou shalt write upon the tables the words which were on the first tables which thou didst break, and thou shalt put them into the ark.
3 So I made an ark of boards of incorruptible wood, and I hewed tables of stone like the first, and I went up to the mountain, and the two tables were in my hand.
4 And he wrote upon the tables according to the first writing the ten commandments, which the Lord spoke to you in the mountain out of the midst of the fire, and the Lord gave them to me.
5 And I turned and came down from the mountain, and I put the tables into the ark which I had made; and there they were, as the Lord commanded me.
