Isaiah 50:5
The Lord GOD hath opened mine ear, and I was not rebellious, neither turned away back.
The Lord God hath opened mine ear,.... To hear most freely, and receive most fully, what is said by him, and to observe and do it: the allusion seems to be to the servant that had his ears bored, being willing to serve his master for ever, Exodus 21:5 which phrase of boring or opening the ear is used of Christ, Psalms 40:6. It is expressive of his voluntary obedience, as Mediator, to his divine Father, engaging in, and performing with the greatest readiness and cheerfulness, the great work of man's redemption and salvation.
and I was not rebellious; not to his earthly parents, to whom he was subject; nor to civil magistrates, to whom he paid tribute; nor to God, he always did the things that pleased him: he was obedient to the precepts of the moral law, and to the penalty of it, death itself, and readily submitted to the will of God in suffering for his people; which obedience of his was entirely free and voluntary, full, complete, and perfect, done in the room and stead of his people; is the measure of their righteousness, and by which they become righteous; is well pleasing to God, and infinitely preferable to the obedience of men and angels:
neither turned away back; he did not decline the work proposed to him, but readily engaged in it; he never stopped in it, or desisted from it, until he had finished it; he did not hesitate about it, as Moses and Jeremy; or flee from it, as Jonah.
