So Samuel turned again after Saul,.... Though he before said he would not, 1-Samuel 15:26 yet he did, changing his mind, as he might without being chargeable with a lie; and he also might have an impulse from the Lord so to do, and which he did not in order to worship with Saul, which it does not appear he did, but rather the contrary; but that Saul might not be despised by the people, and his authority lessened, while he continued king; and that he might do what Saul had neglected to do, destroy Agag: and Saul worshipped the Lord; alone, by offering sacrifice to him.

Samuel turned again after Saul--not to worship along with him; but first, that the people might have no ground, on pretense of Saul's rejection, to withdraw their allegiance from him; and secondly, to compensate for Saul's error, by executing God's judgment upon Agag.

Turned - First, that the people might not upon pretence of this sentence of rejection, withdraw their obedience to their sovereign; whereby they would both have sinned against God, and have been as sheep without a shepherd. Secondly, that he might rectify Saul's error, and execute God's judgment upon Agag.
