And Moses and Aaron came in unto Pharaoh, and said unto him, Thus saith the LORD God of the Hebrews, How long wilt thou refuse to humble thyself before me? let my people go, that they may serve me.

And Moses and Aaron went in unto Pharaoh, and said unto him, Thus saith Jehovah, the God of the Hebrews, How long wilt thou refuse to humble thyself before me? let my people go, that they may serve me.

Therefore Moses and Aaron went in to Pharao, and said to him: Thus saith the Lord God of the Hebrews: How long refusest thou to submit to me? let my people go, to sacrifice to me.

And Moses and Aaron came to Pharaoh, and said to him, Thus saith Jehovah the God of the Hebrews: How long dost thou refuse to humble thyself before me? let my people go, that they may serve me.

And Moses cometh in, Aaron also, unto Pharaoh, and they say unto him, 'Thus said Jehovah, God of the Hebrews, Until when hast thou refused to be humbled at My presence? send My people away, and they serve Me,

Then Moses and Aaron went in to Pharaoh, and said to him, This is what the Lord, the God of the Hebrews, says: How long will you be lifted up in your pride before me? let my people go so that they may give me worship.

Therefore, Moses and Aaron entered to Pharaoh, and they said to him: "Thus says the Lord God of the Hebrews: How long will you be unwilling to be subject to me? Release my people to sacrifice to me.

Venit ergo Moses et Aharon ad Pharaonem, et dixerunt ei, Sic dicit Jehova Deus Hebraeorum, Quousque renuis humiliari coram facie mea? Dimitte populum meum ut serviant mihi.

And Moses and Aaron came in. Moses now relates how, at God's command, he tried whether Pharaoh's heart, after so many experiments, would be bent to obedience out of fear of the new punishment which impended. But by this proof his impiety was better known, since, although he saw his kingdom deprived of a part of its corn, he fears not what is denounced by Moses respecting the other part. Therefore he reproves him still more severely, inquiring, "How long" wilt thou proudly resist the command of God? For since plagues vanquish even the worst natures, it was marvelous that the king, having been smitten eight times, and in so awful a manner, was still unwilling to yield, as if he were in safety, and unaffected by any injury. But we may learn from this passage, that we are chastised with this object by the rods of God, that we may return from the indulgence of our lusts to submission to Him. This Moses calls (and Peter after him, 1-Peter 5:6) to "humble" ourselves before God, or "beneath His mighty hand," when, having experienced His formidable power, we reverently submit ourselves to His dominion. Whence it follows, that they, who are neither tamed nor bent by the fear of punishment., struggle against God as with an iron brow. Let fear, then, teach us to repent; and that we may not provoke His vengeance by proud contempt, let us learn that nothing is more terrible than to fall into His hands. Moses also hints that Pharaoh's contention was not with the Israelites only, but with God who undertook their cause. And let us not doubt, therefore, that all tyrants, who unjustly persecute the Church, contend with God Himself, to whose powers they will find themselves far inferior.

How long wilt thou refuse to humble thyself - Had it been impossible for Pharaoh, in all the preceding plagues, to have humbled himself and repented can we suppose that God could have addressed him in such language as the preceding? We may rest assured that there was always a time in which he might have relented, and that it was because he hardened his heart at such times that God is said to harden him, i.e., to give him up to his own stubborn and obstinate heart; in consequence of which he refused to let the people go, so that God had a fresh opportunity to work another miracle, for the very gracious purposes mentioned in Exodus 10:2. Had Pharaoh relented before, the same gracious ends would have been accomplished by other means.

And Moses and Aaron came in unto Pharaoh, and said unto him, Thus saith the LORD God of the Hebrews, How long wilt thou refuse (b) to humble thyself before me? let my people go, that they may serve me.
(b) The purpose of affliction is that we humble ourselves with true repentance under the hand of God.

And Moses and Aaron came in unto Pharaoh,.... As the Lord commanded them, for what is before said to Moses was designed for Aaron also, his prophet and spokesman:
and said unto him, thus saith the Lord God of the Hebrews; as the ambassadors of the God of Israel, and in his name said:
how long wilt thou refuse to humble thyself before me? to acknowledge his offence, lie low before God, and be subject to his will; he had humbled himself for a moment, but then this did not continue; what God expected of him, and complains of the want of, was such a continued humiliation before him, and such a subjection to him, as would issue in complying with what he had so often demanded of him, and is as follows:
let my people go, that they may serve me; see Exodus 9:1.

As Pharaoh had acknowledged, when the previous plague was sent, that Jehovah was righteous (Exodus 9:27), his crime was placed still more strongly before him: "How long wilt thou refuse to humble thyself before Me?" (לענת for להענת, as in Exodus 34:24).

Thus saith the Lord God of the Hebrews, How long wilt thou refuse to humble thyself before me? - It is justly expected from the greatest of men, that they humble themselves before the great God, and it is at their peril if they refuse to do it. Those that will not humble themselves, God will humble.
