sn The title “my servant” or “servant of the Lord” is reserved in the Bible for distinguished personages, people who are truly spiritual leaders, like Moses, David, Hezekiah, and also the Messiah. Here it underscores Moses’ obedience.
tn The word “faithful” is נֶאֱמָן (ne’eman), the Niphal participle of the verb אָמַן (’aman). This basic word has the sense of “support, be firm.” In the Niphal it describes something that is firm, reliable, dependable—what can be counted on. It could actually be translated “trustworthy.”
