14Therefore, since the children share in flesh and blood, He Himself likewise also partook of the same, so that through death He might destroy the one who has the power of death, that is, the devil, 15and free those who through fear of death were subject to slavery all their lives. 16For clearly He does not give help to angels, but He gives help to the descendant of Abraham. 17Therefore, in all things He had to be made like His brothers so that He might become a merciful and faithful high priest in things pertaining to God, to make propitiation for the sins of the people. 18For since He Himself was tempted in that which He has suffered, He is able to come to the aid of those who are tempted.
Jesus, made like his brothers in every way needs the help of God to complete his mission.
"that He might become..."
How could he 'become' the perfect high priest? Because he was tempted - being able to sin, he was made able to resist sin at every moment leading up to the last hideous test of the cross because of God's provision. We know he could not achieve this on his own. but he did have to seek the help he needed.
in the days of His humanity, He offered up both prayers and pleas with loud crying and tears to the One able to save Him from death, and He was heard because of His devout behaviour. 8Although He was a Son, He learned obedience from the things which He suffered. 9And having been perfected, He became the source of eternal salvation for all those who obey Him Heb 5:7
Angels are not deceived like man is/was. They should have known better than to follow Lucifer into sin/opposition to God.
Being spirit beings, they have full access to God. They are not separated from Him. They don't need help. They don't suffer or have to learn - they should know better than to choose other than God. They were not made needy like humans were. They need no food, sustenance, wisdom, guidance or help.
Jesus, made like us, does need help in everything - as the first fruit on all creation in ascending to be with God - finally holy and without potential for sin anymore.
Jesus from Nazareth, how God anointed Him with the Holy Spirit and with power, who went about doing good and healing all those being oppressed by the devil, because God was with Him. Acts 10:38
