Hebrews 2:17-18 Amplified Bible (AMP)

17. So it is evident that it was essential that He be made like His brethren in every respect, in order that He might become a merciful (sympathetic) and faithful High Priest in the things related to God, to make atonement and propitiation for the people's sins.

18. For because He Himself [in His humanity] has suffered in being tempted (tested and tried), He is able [immediately] to run to the cry of (assist, relieve) those who are being tempted and tested and tried [and who therefore are being exposed to suffering].
