So when David was old and full of days, he made Solomon his son king over Israel.

Commentary

So when David was old and full of days,.... Perhaps was now in the last year of his age, ab out seventy years old, though before he was bedridden; see Ch1 28:2 , he made Solomon his son king over Israel; declared him to be his successor; this was before the affair of Adonijah, for then he ordered him to be anointed king, and placed on the throne; and this aggravated the rebellion of Adonijah, that it was against the declared and known will of his father.
