Therefore will I number you to the sword, and ye shall all bow down to the slaughter: because when I called, ye did not answer; when I spake, ye did not hear; but did evil before mine eyes, and did choose that wherein I delighted not.
Therefore will I number you to the sword. "Number you" - doom you: alluding to the "number," as Meni (Isaiah 65:11) means. Retribution in kind, the punishment answering to the sin (cf. 2 Chronicles 36:14-17).
Because when I called, ye did not answer. "I called," though 'none had called' upon me (Isaiah 64:7), yet even then none 'answered' (Proverbs 1:24). Contrast with this God and His people's mutual fellowship in prayer (Isaiah 65:24).
