1 Chronicles 18:2

And he brought the ram for the burnt offering
One of the two he was ordered to take, ( Leviticus 8:2 )

and Aaron and his sons laid their hands on the head of the ram;
as they had done before on the head of the bullock, see ( Leviticus 8:14 ) their right hands, as the Targum of Jonathan, and that at the same time; not first Aaron and then his sons, as a famous grammarian, Aben Ezra makes mention of, thought; but, as he himself says, they laid them on together.
