Exodus 9:13
And the LORD said unto Moses, Rise up early in the morning, and stand before Pharaoh, and say unto him, Thus saith the LORD God of the Hebrews, Let my people go, that they may serve me.
And the Lord said unto Moses, rise up early in the morning, and stand before Pharaoh,.... Who it seems used to rise early in the morning, and so was a fit time to meet with him, and converse with him; it might be one of the mornings in which he used to go to the water early, though not mentioned, unless that was every morning:
and say unto him, Thus saith the LORD God of the Hebrews, Let my people go, that they may serve me; thus had he line upon line, and precept upon precept, so that he was the more inexcusable, see Exodus 9:1.
