John Gill Commentary Genesis 39:7

"And it came to pass after these things, that his master`s wife cast her eyes upon Joseph; and she said, Lie with me." — Genesis 39:7 (ASV)

And it came to pass after these things. After he was the overseer of his house; in which office, after he had been some time, it happened that his master's wife cast her eyes upon Joseph.

He being a handsome young man, caught her eye, and that her heart, and led her on to lust after him, and frequently fed her eyes with amorous glances at him; and at length being fired with lust, and having an opportunity, she said to him, in a bold and impudent manner, in plain words, having given signs and hints, and dropped expressions tending thereto before, as it is probable: lie with me;

Now directly, there being both opportunity and convenience, perhaps her chamber was near: this was a very great temptation to a young man in single life and living well, from his mistress, who had it greatly in her power to make him should he consent, or ruin him should he deny.
