It seems that Calvin regarded “my holy one,” as equivalent to “my sanctifier;” he who had separated the people from others to be his own. The primary meaning of [קדש] is no doubt to separate a thing from a common use to a sacred one; but whether in this connection it has this meaning is not quite certain. “The holy one of Israel” is a phrase several times used by Isaiah, see chapter 30:11; 43:3, etc. The sentence here may be rendered, “God of my holiness,” or “My God, my holiness.”—Ed.
