John Gill's Bible Commentary Ver. 3. And call Jesse to the sacrifice , etc.] His family, both him and his sons, to partake of the peace offerings; as every offerer had a right to invite his friends, and whomsoever he pleased, to eat of those parts of them which belonged to him, as a feast before the Lord: and I will show thee what thou shall do ; when Jesse and his family were with him: and thou shalt anoint unto me him whom I name unto thee ; that is, anoint him to be king over Israel, whom he should point out so plainly to him, as if he called him by name.
Matthew Henry Commentary
Verses 1-5 - It appears that Saul was grown very wicked. Of what would he not be guilty, who durst think to kill Samuel? The elders of Bethlehe trembled at Samuel's coming. It becomes us to stand in awe of God' messengers, and to tremble at his word. His answer was, I com peaceably, for I come to sacrifice. When our Lord Jesus came into the world, though men had reason to fear that his errand was to condemn the world, yet he gave full assurance that he came peaceably, for he cam to sacrifice, and he brought his offering with him; A body hast tho prepared me. Let us sanctify ourselves, and depend upon His sacrifice.
