Deuteronomy 7:26
11-26. Thou shalt therefore keep the commandments, and the statutes, and the judgments, which I command thee this day—In the covenant into which God entered with Israel, He promised to bestow upon them a variety of blessings so long as they continued obedient to Him as their heavenly King. He pledged His veracity that His infinite perfections would be exerted for this purpose, as well as for delivering them from every evil to which, as a people, they would be exposed. That people accordingly were truly happy as a nation, and found every promise which the faithful God made to them amply fulfilled, so long as they adhered to that obedience which was required of them. See a beautiful illustration of this in Ps 144:12-15.

Let him reap the fruits of his own perverse choice; his case is desperate; say nothing to him (compare Jer 7:16). Here Ho 4:15 shows the address is to Judah, to avoid the contagion of Israel's bad example. He is bent on his own ruin; leave him to his fate, lest, instead of saving him, thou fall thyself (Isa 48:20; Jer 50:8; 51:6, 45; 2Co 6:17).
