(23) Doorkeepers for the ark.--"Porters" (1 Chronicles 15:18). Warders are meant. Obed-edom and Jehiah were also warders of the Ark (1 Chronicles 15:24). In the procession two may have walked in front of it and two behind. They would be responsible for the prevention of all unauthorised approach to the Ark of God.
Verse 23. - Berechiah and Elkanah. It appears from the following verse that there was also another couple of doorkeepers (i.e. persons to protect the openings of the ark, that it should not be opened), viz. Obed-edom and Jehiah.
15:1-24 Wise and good men may be guilty of oversights, which they will correct, as soon as they are aware of them. David does not try to justify what had been done amiss, nor to lay the blame on others; but he owns himself guilty, with others, of not seeking God in due order
And Berechiah, and Elkanah, were doorkeepers for the ark,.... Either while it was at Kirjathjearim, and at Obededom's house; or rather after it was put in the tabernacle David had prepared for it; though it may be best of all to understand it, that those, as it was carrying, went before it, to keep the people from pressing to it, and gazing on it.
