'Three Times' in the Bible

When Daniel knew that the writing was signed, he went into his house (now his windows were open in his chamber toward Jerusalem) and he kneeled on his knees three times a day, and prayed, and gave thanks before his God, as he did before.

Then they answered and said before the king, "That Daniel, who is of the children of the captivity of Judah, doesn't regard you, O king, nor the decree that you have signed, but makes his petition three times a day."
