1 Chronicles 29:22 - Joseph Benson’s Commentary on the Old and New Testaments

And did eat and drink before the Lord Before the ark, in the courts or places as near to it as they conveniently could: or, as in God's presence, in a solemn and religious manner, praising God for this great mercy, and entreating his blessing on this great affair. They made Solomon king the second time The first time was, when he was made king during Adonijah's conspiracy, (1 Kings 1:34,) on which occasion it was done in great haste, and in the presence of only a few of David's servants; but now in the presence of all the great men of Israel, the princes of the tribes, the captains of thousands and hundreds. And anointed him to be the chief governor After the death of David. Perhaps, however, David now resigned the government of the kingdom to him, as he knew he had not long to live. And Zadok to be priest It must be remembered that the high-priest had his vicegerent who might officiate in his stead. So that this action of theirs, the anointing Zadok, did not actually constitute him high- priest, but only settled the reversion of it upon him and his line after Abiathar's death; even as David's making Solomon king, and their anointing Solomon to be the chief governor here, did not put him into actual possession of the kingdom, but only gave him a right to it after the present king's death: hence, notwithstanding this anointing, Abiathar continued to exercise his office till Solomon thrust him out, 1 Kings 2:27.
