Heb. 5:8—“Though he were Son, he learned obedience from the things which he suffered.”
Problem: Though he were Son [i.e., ‘notwithstanding the fact that he was the Son,’ and thus not in a place of obedience or subjection, but co-equal in every way in the eternal relations of the Triune Godhead], he learned obedience [not, ‘learned to obey,’ but ‘learned obedience’ by experience]
from the things which he suffered [on earth as the God-Man].
