Hebrews 10:31

(31) The living God.—As in Hebrews 3:12; Hebrews 9:14 the exact meaning of the writer’s words is “a Living God;” and a reference to the first of these passages (and to Hebrews 4:12) will show clearly what is their force in this place. There can be little doubt that Deuteronomy 32:0, from which he has been quoting, is still in his thought. See Deuteronomy 32:40—“I lift up my hand to heaven, and say, I live for ever.”
