21:20 And Ornan turned back, and saw the angel; and his four sons with him {i} hid themselves. Now Ornan was threshing wheat.
(i) If man hides himself at the sight of an angel who is a creature, how much more as a sinner able to appear before the face of God?
21:20 Hid themselves - Because of the glory and majesty in which the angel appeared, which mens weak natures are not able to bear; and from the fear of God's vengeance which now seemed to be coming to their family.
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.
