Charles Spurgeon Commentary Daniel 6:10

"And 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 upon his knees three times a day, and prayed, and gave thanks before his God, as he did aforetime." — Daniel 6:10 (ASV)

And his windows being open in his chamber toward Jerusalem,

That much-loved city, though now in ruins.

He knelt on his knees three times a day, and prayed, and gave thanks before his God, as he did before. (Daniel 6:10)

It was bravely done. A man in a lesser position might have carried out his devotions in private without sin, but not so Daniel.

He is a representative man: he must not play the coward; it is incumbent upon him to be especially and deliberately public in all that he does, for if he is seen to slink, even in the smallest degree, then all the saints will lose heart.
