Three hundred and ninety days, etc. The days, as stated in Ezekiel 4:6, stand for years according to the symbolism (with which Ezekiel was probably acquainted) of Numbers 14:34. How we are to explain the precise number chosen is a problem winch has much exercised the minds of interpreters. I will begin by stating what seems to me the most tenable solution. In doing this I follow Smend and Cornill in taking the LXX. as giving the original reading, and the Hebrew as a later correction, made with a purpose.
(a) It taught the certainty of the punishment. No plots, or rebellions, or alliances with Egypt, could avert the doom of exile from these who should survive the siege of Jerusalem.
(b) It taught the exiles to accept their punishment with patience, but with hope. There was a limit, and that not very far off, which some of them might live to see, and beyond which there lay the hope of a restoration for both Israel and Judah. If that hope was not realized to the extent which Ezekiel's language impiles, the same may be, said of the language of Isaiah 40-66; whether we refer those chapters to Isaiah himself or to the "great unknown" who followed Ezekiel, and may have listened to his teaching.
