'And he said' means that He so thought. 'My Lord' means the Three in One. 'If now I have found grace in your eyes' means the respectful regard that became a feature of the Lord's state when He took notice of that perception. 'Do not, I beg of you, pass from over your servant' means His intense desire that what He had begun to perceive should not pass away, 'servant' meaning the Lord's human before it was made Divine.
