The order of the parts of the verse can be reversed. Alternate translation: "you will deny three times that you know me before the rooster crows this day"
This can be stated positively. Alternate translation: "the rooster will crow this day only after you deny" or "before the rooster crows today, you will deny"
Here, the crowing of the rooster refers to a certain time of day. Roosters often crow just before the sun appears in the morning. Therefore, this refers to dawn. (See: [[rc://en/ta/man/translate/figs-metonymy]])
# rooster
a bird that calls out loudly around the time the sun comes up
The Jewish day begins at sunset. Jesus was speaking after the sun had set. The rooster would crow just before morning. The morning was part of "this day." Alternate translation: "tonight" or "in the morning" (See: [[rc://en/ta/man/translate/figs-explicit]])
