14 Inasmuch then as the children have partaken of flesh and blood, He Himself likewise shared in the same, that through death He might destroy him who had the power of death, that is, the devil, 15 and release those who through fear of death were all their lifetime subject to bondage. 16 For indeed He does not give aid to angels, but He does give aid to the seed of Abraham. 17 Therefore, in all things He had to be made like His brethren, that He might be a merciful and faithful High Priest in things pertaining to God, to make propitiation for the sins of the people. 18 For in that He Himself has suffered, being tempted, He is able to aid those who are tempted.
Because Jesus Himself suffered when He was tempted, He is able to help those who are being tempted.
Because Jesus Himself in His humanity has suffered in being tempted, He is able to help and provide immediate assistance to those who are being tempted and exposed to suffering.
