1 Samuel 15:20

20 And Saul said to Samuel, Yes, I heard the voice of the Lord, and I have gone in the way, by which the Lord sent me, and I have brought Agag, the king of Amalek, and I have killed Amalek. (And Saul said to Samuel, Yes, I did listen to the Lord's voice, and I have gone on the way where he sent me, and I have brought Agag, the king of the Amalekites here, and I have killed all the other Amalekites.)

1 Samuel 15:20 Meaning and Commentary

1 Samuel 15:20

And Saul said to Samuel, yea, I have obeyed the voice of the
Lord
Here Saul breaks in upon Samuel before he had declared all that the Lord had said unto him; for having expostulated with him for not obeying the voice of the Lord, he could not forbear interrupting him, but with the utmost assurance affirms he had obeyed the voice of the Lord; but then it was very imperfectly, and poor proof does he give of it:

and have gone the way which the Lord sent me;
it is very true he went into the country of Amalek, but he did not do there all the Lord commanded him:

and have brought Agag the king of Amalek;
took him alive, and brought him captive; whereas he ought to have destroyed him at once, and not have reserved him for triumph; a sad proof this of his obeying the voice of the Lord:

and have utterly destroyed the Amalekites;
all that came in his way, in which he did right; but then he had not destroyed the principal of them, their king.

1 Samuel 15:20 In-Context

18 and the Lord sent thee into the way, and said, Go thou, and slay the sinners of Amalek, and thou shalt fight against them till to the slaying of them. (and the Lord sent thee on the way, and said, Go thou, and kill those sinners, the Amalekites, and thou shalt fight against them until they all be slaughtered.)

19 Why therefore heardest thou not the voice of the Lord, but thou were turned to the prey (but instead, thou took that prey), and (so) didest evil in the eyes of the Lord?

20 And Saul said to Samuel, Yes, I heard the voice of the Lord, and I have gone in the way, by which the Lord sent me, and I have brought Agag, the king of Amalek, and I have killed Amalek. (And Saul said to Samuel, Yes, I did listen to the Lord's voice, and I have gone on the way where he sent me, and I have brought Agag, the king of the Amalekites here, and I have killed all the other Amalekites.)

21 Forsooth the people took of the prey, sheep and oxen, the first fruits/the chief fruits of those things that be slain, that they make sacrifice to their Lord God in Gilgal. (But the people kept of the prey, sheep and oxen, the first fruits/the chief fruits of those things that should be killed, to offer as a sacrifice to the Lord their God here in Gilgal.)

22 And Samuel said, Whether the Lord will burnt sacrifices, either slain sacrifices, and not more, rather, that men obey to the voice of the Lord? (And Samuel said, Desireth the Lord burnt sacrifices, and slain sacrifices, or rather, that people obey his voice?) Forsooth obedience to him is better than sacrifices, and to take heed to his word is more than to offer the inner fatness of rams;
