This is how exegesis is done? Thank you.
Here is Gill on the matter:
yet learned he obedience; not to his parents, or civil magistrates, though that is true; nor merely to the precepts of the law, which he did; but unto death: through sufferings he became obedient to death, even the death of the cross: and this he learnt; not that he was ignorant of the nature of it; nor was he destitute of an obedient disposition to it; but the meaning is, he had an experience of it, and effected it; and which was voluntary, and done in our room and stead; and is the rule and the measure of our righteousness before God.
