1-я Царств 3:12

On that day I will perform against Eli all that I have spoken concerning his house (see Sa1 2:30.), beginning and finishing it," i.e., completely. דּבּר את־אשׁר הקים, to set up the word spoken, i.e., to carry it out, or accomplish it. In Sa1 3:13 this word is communicated to Samuel, so far as its essential contents are concerned. God would judge "the house of Eli for ever because of the iniquity, that he knew his sons were preparing a curse for themselves and did not prevent them." To judge on account of a crime, is the same as to punish it. עד־עולם, i.e., without the punishment being ever stopped or removed. להם מקללים, cursing themselves, i.e., bringing a curse upon themselves. "Therefore I have sworn to the house of Eli, that the iniquity of the house of Eli shall not (אם, a particle used in an oath, equivalent to assuredly not) be expiated by slain-offerings and meat-offerings (through any kind of sacrifice) for ever." The oath makes the sentence irrevocable. (On the facts themselves, see the commentary on Sa1 2:27-36.)

In the foregoing chapter we had Samuel a young priest, though by birth a Levite only, for he ministered before the Lord in a linen ephod; in this chapter we have him a young prophet, which was more, God in an extraordinary manner revealing himself to him, and in him reviving, if not commencing, prophecy in Israel. Here is, I. God's first manifestation of himself in an extraordinary manner to Samuel (Sa1 3:1-10). II. The message he sent by him to Eli (Sa1 3:11-14). III. The faithful delivery of that message to Eli, and his submission to the righteousness of God in it (Sa1 3:15-18). IV. The establishment of Samuel to be a prophet in Israel (Sa1 3:19-21).
