This is written Deu_6:16. To make an undue and unwarrantable trial of God, is to tempt God, whether the trial respecteth his power or his goodness; thus the word is used, Num_14:22Psa_78:18Isa_7:12Mat_16:1. By this answer Christ lets the devil know that he abused Scripture in his quotation of it; such as casting of himself down, when he had a plain way to go down by the stairs, would not have been an act of faith, but presumption; not a trusting God upon his word, but a tempting of God, expressly contrary to his command, Deu_6:16.
