Exodus 15:2

The Lord. Here the abbreviated form of God’s name, Yah, appears for the first time in the OT narrative. It is occasionally used in poetic language on account of the rhythm, and also as an ending for personal and even topographical names, as for example, Abijah, Ahaziah, Hezekiah, Zedekiah, Mt. Moriah, etc. (see pp. 35, 173).

And I will prepare him an habitation. These words are the translation of a single Hebrew word. This illustrates the compactness of Hebrew poetry. The KJV rendering seems to have come originally from the Aramaic Targum of Onkelos, who paraphrased the single word of the text by the expression, “I will build him a sanctuary.” Though this may have been one of the meanings of the verb, most translators since the days of the LXX and the Vulgate, including most modern commentators, have preferred the basic meaning of the verb, “beauty.” Accordingly, they translate the expression, “I will glorify him,” or “I will praise him” (RSV).
