V. 12.— Take heed, brethren, lest there be in any of you an evil heart of unbelief in departing from the living God. Upon the quotation which the Apostle had made from Psalms 95 :, he founds an exhortation against there being in any of the believing Hebrews an evil heart of unbelief in departing from the living God. Israel were excluded from Canaan by unbelief. They had the promise of God on which to rely; but, on hearing the report of the spies, respecting the fortified cities, and the prowess of the Canaanites, they determined to make a captain and return to Egypt. There could not, therefore, have been a more suitable foundation for the exhortation against an evil heart of unbelief. The fears and apprehensions of Israel led them to disregard the promises of God, and to determine to act in direct opposition to their deliverer. The believing Hebrews stood by faith, and, if they let slip the truth, must necessarily fall.
