When the days of their feasting were gone about— As the days of their feasting went about. By sanctifying them is meant, his preparing them, by lustrations and other ritual ceremonies, to perform divine service with him, and to render God propitious to them; see Exodus 19:10 and 1 Samuel 16:5 where to sanctify, or cleanse, is used for the care of approaching to sacred rites, washed and clean. The Hebrew word כרךֶ barek, signifies, to bless; but it here implies, to renounce, or bid adieu to, because we bid adieu to, or take our leave of, those things which we abandon or renounce. It is therefore used with great elegance in this sense, to signify, they renounced God; and this signification is still softened, and rendered more elegant, by the addition of the words in their hearts. Thus did Job continually, means every year; that is, on every annual return of each of his sons' birth-days. See Schultens.
