Now when Daniel knew that the writing was signed, he went into his house; and his windows being open in his chamber toward Jerusalem, he kneeled upon his knees three times a day, and prayed, and gave thanks before his God, as he did aforetime.
Now when Daniel knew that the writing was signed - and that, therefore, the power of advising the king against it was taken from him,
He went into his house - withdrawing from the God-dishonouring court.
And, his windows being open - not in vain-glory, but that there might be no obstruction to his view of the direction in which Jerusalem, the earthly seat of Yahweh under the Old Testament, lay, and that the sight of heaven might draw off his mind from earthly thoughts. To Christ in the heavenly temple let us turn our eyes in prayer from this land of our captivity (1 Kings 8:44; 1 Kings 8:48, "If they (thy people) shall bethink themselves in the land where they were carried captive ... and pray unto thee toward their land ... the city and the house which I have built for thy name, then hear thou their prayer;"2 Chronicles 29:34,38; Psalms 5:7).
In his chamber - the upper room where prayer was generally offered by the Jews (Acts 1:13). Not on the house-top (Acts 10:9), where he would be conspicuous.
He kneeled upon his knees - humble attitudes in prayer become humble suppliants. Three times a day - (Psalms 55:17). The three times of prayer were the third, sixth, and ninth hours; our nine, twelve, and three o'clock (Acts 2:15; Acts 10:9; Acts 3:1; Acts 10:30: cf. Daniel 9:21).
Prayed, and gave thanks before his God, as he did aforetime - not from contempt of the king's command, but in accordance with his fixed habit long before it was issued.
