Psalms 105:19

Until the time that his word came,.... Either the word of Joseph, interpreting the dreams of the butler and baker, till that came to be fulfilled; so the Syriac version, "till his word was proved by the event": or rather till the fame and report of that came to Pharaoh's ears, Genesis 41:13, or else the word of the Lord, concerning his advancement and exaltation, signified in dreams to him,

Genesis 37:7, as it follows:

the word of the Lord tried him: it tried his faith and patience before it was accomplished; and when it was, it purged him and purified him, as silver in a furnace, and cleared him of the imputation and calumny of his mistress; for, even in the view of Pharaoh, he appeared to be a man in whom the Spirit of God was, Genesis 41:38. Some think that Christ, the essential Word, is intended, who came and visited him, tried and cleared him.
