Exodus 10:18 - Exposition

He … intreated the Lord . Moses complied, though Pharaoh had this time made no distinct promise of releasing the people. He had learnt that no dependence was to be placed on such promises, and that it was idle to exact them. If anything could have touched the dull and hard heart of the king, it would have been the gentleness and magnanimity shown by Moses in uttering no word of reproach, making no conditions, but simply granting his request as soon as it was made, and obtaining the removal of the plague.
