Exodus 11:8

All these thy servants Thy courtiers and great officers: The people that follow thee That are under thy conduct and command.

When Moses had thus delivered his message, he went out from Pharaoh in great anger, though he was the meekest of all the men of the earth. Probably he expected that the very threatening of the death of the firstborn should have wrought upon Pharaoh to comply; especially he having complied so far already, and having seen how exactly all Moses's predictions were fulfilled. But it had not that effect; his proud heart would not yield, no, not to save all the firstborn of his kingdom. Moses hereupon was provoked to a holy indignation, being grieved, as our Saviour afterward, for the hardness of his heart, Mark 3:5.
