בחצי הלילה

The Gemara suggests several ways to resolve this contradiction. Rabbi Oshaya said that Rabbi Aḥa said: David said as follows: Midnight never passed me by in my sleep. Sometimes I fulfilled the verse, “I rose with the neshef and cried,” but I always, at least, fulfilled the verse, “At midnight I rise to give thanks for Your righteous laws.” Rabbi Zeira said: Until midnight, David would doze like a horse, as a horse dozes, but never sleeps deeply. From midnight on, he would gain the strength of a lion. Rav Ashi said: Until midnight, he would study Torah, as it is written: “I rose with the neshef and cried, I hoped for Your word,” and from midnight on, he would engage in songs and praise, as it is written: “At midnight I rise to give thanks.” To this point, the discussion has been based on the assumption that neshef means evening. The Gemara asks: Does neshef really mean evening? Doesn’t neshef mean morning? As it is written: “And David slew them from the neshef until the evening of the next day” (I Samuel 30:17). Doesn’t this verse mean from the morning until the night, in which case neshef must mean morning? The Gemara responds: No, this verse means that David slew them from one evening until the next evening. The Gemara rejects this response: If so, let the verse be written: From the neshef until the neshef, or from the evening until the evening. Why would the verse employ two different terms for a single concept? Rather, Rava said: There are two times referred to as neshef, and the word can refer to either evening or morning. Neshef must be understood in accordance with its Aramaic root: The night moves past [neshaf ] and the day arrives, and the day moves past [neshaf ] and the night arrives. When King David said: At midnight I rise, the assumption is that he rose precisely at midnight. The Gemara asks: Did David know exactly when it was midnight? Even Moses our teacher did not know exactly when it was midnight. How do we know this about Moses? As it is written that he said to Pharaoh: “Thus said the Lord: About midnight, I will go out into the midst of Egypt” (Exodus 11:4). The word about indicates that it was only an approximation. The Gemara clarifies: What is the meaning of the expression: About midnight? Did Moses say it or did God say it? If we say that the Holy One, Blessed be He, Himself, said: About midnight, to Moses, is there doubt before God in heaven? Rather, this must be understood as follows: God told Moses: At midnight, but from the fact that when Moses came to Pharaoh he said: About midnight; apparently, Moses was uncertain about the exact moment of midnight. Moses, the greatest of all the prophets, was uncertain, and David knew? The Gemara offers several answers to this question:
David had a sign indicating when it was midnight. As Rav Aḥa bar Bizna said that Rabbi Shimon Ḥasida said: A lyre hung over David’s bed, and once midnight arrived, the northern midnight wind would come and cause the lyre to play on its own. David would immediately rise from his bed and study Torah until the first rays of dawn.
Once dawn arrived, the Sages of Israel entered to advise him with regard to the various concerns of the nation and the economy. They said to him: Our master, the king, your nation requires sustenance.
He said: Go and sustain one another, provide each other with whatever is lacking.
The Sages of Israel responded to him with a parable: A single handful of food does not satisfy a lion, and a pit will not be filled merely from the rain that falls directly into its mouth, but other water must be piped in (ge’onim). So too, the nation cannot sustain itself using its own resources.
King David told them: Go and take up arms with the troops in battle in order to expand our borders and provide our people with the opportunity to earn a livelihood.
