Matthew Poole and continuators on Daniel 10:12

12 Then said he unto me, Fear not, Daniel: for from the first day that thou didst set thine heart to understand, and to chasten thy self before thy God, thy words were heard, and I am come for thy words.

The Lord is quick in hearing the fervent prayer of an humble Soul, though he doth not presently let them know it. God heard the first day though he sent not his Angel to tell Daniel of it till three weeks after. 2, A Soul that would obtain great things from God by Prayer, must be solemn, and fervent in seeking God. 3, The fervent and constant Prayers of the Saints, make God to send from Heaven and save. Thus in Peters case, Acts 12.5, 6, 7. to verse 15. and here in Daniels.
