And they met Moses and Aaron, who stood in the way, as they came forth from Pharaoh:

Jamieson-Fausset-Brown Bible Commentary

20, 21. they met Moses . The Lord look upon you, and judge-Thus the deliverer of Israel found that this patriotic interference did, in the first instance, only aggravate the evil he wished to remove, and that instead of receiving the gratitude, he was loaded with the reproaches of his countrymen. But as the greatest darkness is immediately before the dawn, so the people of God are often plunged into the deepest affliction when on the eve of their deliverance; and so it was in this case.

Matthew Henry's Concise Commentary

5:10-23 The Egyptian task-masters were very severe. See what need we have to pray that we may be delivered from wicked men. The head-workmen justly complained to Pharaoh: but he taunted them. The malice of Satan has often represented the service and worship of God, as fit employment only for those who have nothing else to do, and the business only of the idle; whereas, it is the duty of those who are most busy in the world. Those who are diligent in doing sacrifice to the Lord, will, before God, escape the doom of the slothful servant, though with men they do not. The Israelites should have humbled themselves before God, and have taken to themselves the shame of their sin; but instead of that, they quarrel with those who were to be their deliverers. Moses returned to the Lord. He knew that what he had said and done, was by God's direction; and therefore appeals to him. When we find ourselves at any time perplexed in the way of our duty, we ought to go to God, and lay open our case before him by fervent prayer. Disappointments in our work must not drive us from our God, but still we must ponder why they are sent.
