Until the time that his word came — i.e., until his (Joseph’s) interpretation of the dreams was fulfilled (Genesis 41:12). (For the expression “his word came,” equal to “came to pass,” comp. Judges 13:12.)
Word of the Lord. — As a different Hebrew word from that in the previous clause is used, better render, saying (or, oracle) of Jehovah.
Tried him. — Better, purified him, i.e., proved him innocent of the charge for which he was imprisoned. (For this sense of the verb, see Psalms 17:3; Psalms 18:30; Proverbs 30:5, margin.) The psalmist means that by enabling him to foretell the dreams of Pharaoh’s servants, God brought about the proof of his innocence.
