Matthew Poole and continuators on 1 Samuel 16:5

5 And he said, Peaceably: I am come to sacrifice unto the LORD: sanctifie your selves , and come with me to the sacrifice : and he sanctified Jesse and his sons, and called them to the sacrifice .

Prepare your selves in the manner expressed, Exod. 19. 14, 15.

Heb. in the Sacrifice; i. e. joyn with me in this act of Worshipping God, and offering this Sacrifice, thereby to give Thanks for the Blessings you have received from him, and to pray for what you want.

It seems evident, that there was something peculiar in Iesse's Invitation. For First, Both he and his Sons were Invited, whereas the others are onely Invited for their own Persons. Secondly, The different Phrase here used, that he Sanctified these, when he onely bad the other Sanctify themselves; argues a singular care and agency of Samuel in their Sanctification: (unless we should say, He sanctified them, is no more but that he caused them to be Sanctified, that is, these in particular amongst others). Which makes it probable, that the rest were onely to joyn with him in the act of Sacrificing; but these, and onely these, were Invited to Feast upon the remainders of the Sacrifice; which Feast is here called a Sacrifice, as it is above verse 3. And the onely inconvenience of this Interpretation, is, that the word Sacrifice is taken in different senses in the same Verse, which is no unusual thing. See Matth. 8. 22. And this difference may possibly be intimated by the differing prepositions prefixed to the same word, the first being Bazzabach, and the latter Lazzabach. Howsoever, that onely Iesse and his Sons were present at the Feast, may seem probable, from Samuel's design of Privacy, and from the following Relation.
