Exodus 2:23

The king of Egypt died — And after him, one or two more of his sons or successors. And the children of Israel sighed by reason of bondage — Probably the murdering of their infants did not continue, that part of their affliction only attended the birth of Moses, to signalize that. And now they were content with their increase, finding that Egypt was enriched by their labour; so they might have them for their slaves, they cared not how many they were. On this therefore they were intent, to keep them all at work, and make the best hand they could of their labour. When one Pharaoh died, another rose up in his place, that was as cruel to Israel as his predecessors. And they cried — Now at last they began to think of God under their troubles, and to return to him from the idols they had served, Ezekiel 20:8. Hitherto they had fretted at the instruments of their trouble, but God was not in all their thoughts. But before God unbound them, he put it into their hearts to cry unto him. It is a sign God is coming towards us with deliverance, when he inclines us to cry to him for it.
