1 And it came to pass in the month Nisan, in the twentieth year of Artaxerxes the king, that wine was before him: and I took up the wine, and gave it unto the king. Now I had not been beforetime sad in his presence.
Now it happened in the month of Nisan, etc. Nisan is the first month of the year according to the Hebrews, in which they always used to celebrate Passover, which we call April. Therefore, what was said above, that he mourned, fasted, and prayed for many days, it is evident indeed that for four continuous months, namely the ninth, tenth, eleventh, and twelfth, he devoted himself to this most sacred dedication, awaiting the opportune time in which he could express his desire to the king. And indeed, he was the chief cupbearer, he used to hand the cup to the king, performing the duty of joy outwardly, but inwardly he was weighed down with severe sadness, because he remembered the holy city as destroyed and the people of God given over to reproach and contempt by the enemies of God. Hence, with those like him, he declares speaking in the Psalm: "By the rivers of Babylon, there we sat down and wept, when we remembered Zion" (Psalm 136).
