1 Samuel 15:2-3

2 Thus saith the LORD of hosts, I remember that which Amalek did to Israel, how he laid wait for him in the way, when he came up from Egypt.
3 Now go and smite Amalek, and utterly destroy all that they have, and spare them not; but slay both man and woman, infant and suckling, ox and sheep, camel and ass.

1 Samuel 15:2-3 Meaning and Commentary

INTRODUCTION TO FIRST SAMUEL 15

In this chapter are recorded the order Saul had from the Lord to destroy Amalek utterly, 1Sa 15:1-3 the preparation he made to put it in execution, and the success thereof, 1Sa 15:4-9 the offence the Lord took at his not obeying his order thoroughly, with which Samuel was made acquainted, and which grieved him, 1Sa 15:10,11, upon which he went out to meet Saul, and reprove him; and a long discourse upon the subject passed between them, the issue of which was, that by an irrevocable decree he was rejected from being king, 1Sa 15:12-31 and the chapter is concluded with an account of Samuel's hewing in pieces Agag king of Amalek, and of his final departure from Saul, 1Sa 15:32-35.
