Acts 7:10

‘And delivered him out of all his afflictions, and gave him favour and wisdom before Pharaoh king of Egypt, and he made him governor over Egypt and all his house.'

Thus God delivered him from his afflictions, and exalted him, and enthroned him (the parallel could hardly be missed with the One Who had been crucified and was declared by His followers to have been enthroned, although at this stage Stephen is not trying to make it too blatant). He was delivered in such a way that the great Pharaoh himself looked on him with favour and saw him as wise. And he made him Lord over Egypt and all his house. The one rejected by Israel's leaders was uplifted and exalted, and became the favoured of the unorthodox. (This was getting right to the heart of the charge against Stephen).

‘Favour (grace) and wisdom.' This may be a specific reference to Joseph's ability to interpret Pharaoh's dreams. God showed Pharaoh that Moses was favoured by Him by giving him the ability to reveal signs and wonders before Pharaoh in interpreting dreams. Compare Acts 7:36.
