Daniel 10:11-12

And he said unto me, O Daniel, thou man greatly beloved, understand the words that I speak unto thee, and stand upright; for unto thee am I now sent: and when he had spoken this word unto me, I stood trembling. Then said he unto me, Fear not, Daniel; for from the first day that thou didst set thine heart to understand, and, to humble thyself before thy God, thy words were heard: and I am come for thy words' sake.
