Son of man, write thee the name of the day
That is, what day of the week it was, as well as what day of the month; as whether the first, or second, or third: for the Jews had no other names for their days, as we have: even of this same day;
according to Bishop Usher F18, it was the 30th of January, and the fifth day of the week (Thursday); A.M. 3414, or 590 before Christ. Mr. Whiston F19 places it at 3413 A.M. or 591 before Christ. The prophet is bid to observe it punctually, and write it exactly, that there might be no mistake; to set it down in his pocket book; or it may be in some public register, that it might not only be remembered by him, but known by the people; that so when they should hear the fact afterwards related, and exactly agreeing with this prediction, they would acknowledge him to be a true prophet; since this would be a confirmation of the word of the Lord coming to him: the king of Babylon set himself against Jerusalem this same day;
or "drew nigh" F20; brought up his army to it, and laid siege against it, and prepared everything to carry it on; which he very probably did in person, though he afterwards retired, and left the command of his army with his generals; and this was exactly the day before mentioned; see ( 2 Kings 25:1 ) ( Jeremiah 39:1 ) ( 52:4 ) . The Prophet Ezekiel was now in Chaldea, many miles from Judea, and yet had this account the very selfsame day, even from the Lord himself, who is omniscient and omnipresent.
