(18-27) The purchase of Ornan's threshingfloor as a place of sacrifice.
(18) Then the angel of the Lord commanded Gad to say to David.--Rather, Now the angel had told Gad to tell David. In Samuel, the mediation of the angel is not mentioned. There we read, "And Gad came that day to David, and said unto him, Go up," &c. No doubt it is only in the later prophetical books of the Canon that angels are introduced as the medium of communication between God and His prophets. (See Daniel 8:16, ix, 21; Zechariah 1:9; Zechariah 1:12, &c.; but comp. Judges 6:11; Judges 6:14; Judges 6:16, &c., and Genesis 18:1-2; Genesis 18:13; Genesis 32:24; Genesis 32:30.)
21:1-30 David's numbering the people. - No mention is made in this book of David's sin in the matter of Uriah, neither of the troubles that followed it: they had no needful connexion with the subjects here noted. But David's sin, in numbering the people, is related: in the atonement made for that sin, there was notice of the place on which the temple should be built. The command to David to build an altar, was a blessed token of reconciliation. God testified his acceptance of David's offerings on this altar. Thus Christ was made sin, and a curse for us; it pleased the Lord to bruise him, that through him, God might be to us, not a consuming Fire, but a reconciled God. It is good to continue attendance on those ordinances in which we have experienced the tokens of God's presence, and have found that he is with us of a truth. Here God graciously met me, therefore I will still expect to meet him.
