His windows being open in his chamber toward Jerusalem, he kneeled upon his knees three times a day, and prayed.@Daniel 6:10

Philip P. Bliss, Gospel Hymns No. 2 (New York: Biglow & Main, 1876), number 10 (🔊 pdf nwc).

Mr. and Mrs. Bliss came to Chicago to attend the Christian convention called by [Dwight L.] Moody. During the session he made an address on the use of song in worship; and sang at the prayer meeting of ministers in Farwell Hall, presided over by Mr. Moody…Over a thousand ministers were present, and the intense spiritual feeling prevailing found fit expression through Bliss in song. After he had sung Are Your Windows Open toward Jerusalem? his own soul thrilled by the conscious presence of the Holy Spirit, one dear minister cried out, God bless Mr. Bliss for that song; and scores of amens came from as many earnest, tender hearts. This was the last time he sang in Chicago. None who were present in Farwell Hall that forenoon will ever forget the power with which he sang. Mr. Moody leaned forward in his chair, occupied with the song and the singer, and overcome by the feeling produced by the music and the sentiment of the hymn. It was the last time he was to hear him this side of the River.…

The [song] was suggested to Mr. Bliss while attending a Sunday service at the State Prison in Joliet, Illinois, where he had gone to sing. Mr. H. G. Spafford, of Chicago, addressed the prisoners, and used Daniel in Babylon, as an illustration to them of Gospel truth, and asked the question in closing—Are your windows open toward Jerusalem?

Philip P. Bliss (1838–1876)

Do you see the Hebrew captive kneeling,
At morning, noon and night, to pray?
In his chamber he remembers Zion,
Though in exile far away.


Are your windows open toward Jerusalem,
Though as captives here, a little while we stay?
For the coming of the King in His glory
Are you watching day by day?


Do not fear to tread the fiery furnace,
Nor shrink the lion’s den to share;
For the God of Daniel will deliver,
He will send His angel there.


Children of the living God, take courage,
Your great deliverance sweetly sing.
Set your faces toward the hill of Zion,
Thence to hail your coming king.
