Here's a literal translation:
From which he owed according to all to be likened to the brethren, that he should become a merciful and faithful high priest in the things towards God, so as to atone the sins of the people. Hebrews 2:17
This word means
similar, not
exactly. Jesus was fully man, but he was only
similar to sinful man.

1. homoioo (ὁμοιόω, 3666), “to make like” (akin to A, No. 1), is used (a) especially in the parables, with the significance of comparing, “likening,” or, in the passive voice, “being likened,” Matt. 7:24, 26; 11:16; 13:24; 18:23; 22:2 (RV, “likened”); 25:1; Mark 4:30; Luke 7:31; 13:18, RV, “liken” (KJV, “resemble”); v. 20; in several of these instances the point of resemblance is not a specific detail, but the whole circumstances of the parable; (b) of making “like,” or, in the passive voice, of being made or becoming “like,” Matt. 6:8; Acts 14:11, “in the likeness of (men),” lit., “being made like” (aorist participle, passive); Rom. 9:29; Heb. 2:17, of Christ in being “made like” unto His brethren, i.e., in partaking of human nature, apart from sin (cf. v. 14).
