מדרש אויף דניאל 10:3

“It is I [who has] installed [in Hebrew: נסכתי] My king” (Psalms 2:6). What does “נסכתי” mean? [It means] “I have anointed him,” as [can be seen from the fact that Daniel] said [of himself that] “I have not anointed myself” [and he used the word סכתי] (Daniel 10:3). Alternatively, [it means], “I have cast him [as one would cast a molten metallic object],” as it is said [of the golden calf that it was], “a molten calf” (Exodus 32:4) [using the word מסכה]. Alternatively, [it means], “I have ennobled him,” as it is said, “eight princes of men” (Micah 5:4) [using the word נסיכי]. And it is written, “The princes of the north are there” (Ezekiel 32:30) [also using the word נסיכי]. And where did He ennoble him? “On My holy mountain, Zion” (Psalms 2:6).

What is, “in all of our calling to Him”? The Rabbis said: There is prayer that is answered after forty days. From whom do you derive this? From Moses, as it is written: “I fell before the Lord, as at the first, forty days…” (Deuteronomy 9:18).³³The following verse concludes: “And the Lord heeded me that time as well” (Deuteronomy 9:19). There is prayer that is answered after twenty days. From whom do you derive this? From Daniel, as it is written: “I ate no tasty bread…until the completion of three weeks of days” (Daniel 10:3), and then he said: “Lord, hear; Lord, forgive…” (Daniel 9:19). There is prayer that is answered after three days. From whom do you derive this? From Jonah, as it is written: “Jonah was in the innards of the fish [for three days and three nights]” (Jonah 2:1). And then: “Jonah prayed to the Lord his God from the innards of the fish” (Jonah 2:2). There is prayer that is answered after one day. From whom do you derive this? From Elijah, as it is written: “[It was at the time of offering up the afternoon offering] that Elijah the prophet approached, and he said…[Today it will be known that You are God in Israel]” (I Kings 18:36). There is prayer that is answered after one time period.³⁴This is one twelve-hour period, either one day or one night. From whom do you derive this? From David, as it is written: “But as for me, let my prayer come to You, Lord, at a time of favor” (Psalms 69:14). There is a prayer that even before it is expressed from his mouth, the Lord will answer, as it is stated: “It will be, before they call, I will answer” (Isaiah 65:24).
