The number three in the Bible represents completeness. That's why Jesus rose on the third day after the Crucifixion -- his transformation was complete. It's why Elijah stretched himself on the dead child three times, why Jonah was in the belly of the fish for three days, why the Lord called Samuel three times, and many more. It's also reflected in the fact that there are three levels of heaven, three levels of hell, three levels to human life and, ultimately, three aspects of the Lord Himself: Father, Son and Holy Spirit.

10563. 'And also you have found grace in My eyes' means that he was accepted because he had the ability to head that nation. This is clear from the meaning of 'finding grace in Jehovah's eyes' as being accepted, at this point on account of his character, meant by 'I know you by name'. That character was such that he had the ability to head that nation; for the Lord foresaw that Moses would head the Israelite people. His foresight of this is evident from the fact that Moses was brought up in the court of Pharaoh the king where rule was exercised, and where he gained an air of authority over others. It was for this reason also that he was accepted to head that nation. In addition to this his character was such that he was better able than others from that nation to receive what would be uttered by the Divine, for the external in his case was not so separate from the internal as it was with that nation. These therefore are the considerations that are meant by 'I know you by name, and also you have found grace in My eyes'.
