isaiah 28:15 Because ye have said, We have made a covenant with death, and with hell are we at agreement; when the overflowing scourge shall pass through, it shall not come unto us: for we have made lies our refuge, and under falsehood have we hid ourselves: - Free Bible Online

      15. said--virtually, in your conduct, if not in words.
      covenant--There may be a tacit reference to their confidence in their "covenant" with the Assyrians in the early part of Hezekiah's prosperous reign, before he ceased to pay tribute to them, as if it ensured Judah from evil, whatever might befall the neighboring Ephraim (Isa 28:1). The full meaning is shown by the language ("covenant with death--hell," or sheol) to apply to all lulled in false security spiritually (Ps 12:4; Ec 8:8; Jer 8:11); the godly alone are in covenant with death (Job 5:23; Ho 2:18; 1Co 3:22).
      overflowing scourge--two metaphors: the hostile Assyrian armies like an overwhelming flood.
      pass through--namely, through Judea on their way to Egypt, to punish it as the protector of Samaria (2Ki 17:4).
      lies--They did not use these words, but Isaiah designates their sentiments by their true name (Am 2:4).
