Charles Ellicott Commentary Daniel 9:20

"And while I was speaking, and praying, and confessing my sin and the sin of my people Israel, and presenting my supplication before Jehovah my God for the holy mountain of my God;" — Daniel 9:20 (ASV)

Whiles I was speaking.— The answer to Daniel’s prayer. He had not even finished his prayer when the answer came. The angel Gabriel, whom he had seen (Daniel 8:16), comes to him, and reveals to him the mystery of the seventy weeks.
