Many liberal theologians argue that the book of Daniel in the Old Testament was written about 150BC instead of roughly 500BC when it claims to have been written, or that the book of Daniel is an outright fraud. This argument is not correct.
VALIDITY OF THE BOOK OF DANIEL
Is It Real or Is It Fake?
The Book of Daniel Was Included:
The book of Daniel was Included in the Septuagint (Greek translation of the Old Testament), written in 277 BC.
The Book of Daniel was also included in the Masoretic Text.
Jesus quoted from it several times:
When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand:) (Matthew 24:15, from Daniel 11:31)
Jesus saith unto him, Thou hast said: nevertheless I say unto you, Hereafter shall ye see the Son of man sitting on the right hand of power, and coming in the clouds of heaven. (Matthew 26:64, from Daniel 7:13)
But when ye shall see the abomination of desolation, spoken of by Daniel the prophet, standing where it ought not, (let him that readeth understand,) then let them that be in Judaea flee to the mountains: (Mark 13:14, from Daniel 11:31) (may be same quote as Matthew 24:15)
And then shall they see the Son of man coming in the clouds with great power and glory. (Mark 13:26, from Daniel 7:13)
And Jesus said, I am: and ye shall see the Son of man sitting on the right hand of power, and coming in the clouds of heaven. (Mark 14:62, from Daniel 7:13) (may be same quote as Matthew 26:64)
In Matthew 26:64 and Mark 14:62, the high priest knew exactly what Jesus was quoting, which was why he accused Jesus of blasphemy. If the Book of Daniel were a fraud, the high priest and especially Jesus would have known this.
Equivalent verses from the Book of Daniel:
I saw in the night visions, and, behold, one like the Son of man came with the clouds of heaven, and came to the Ancient of days, and they brought him near before him. (Daniel 7:13)
And arms shall stand on his part, and they shall pollute the sanctuary of strength, and shall take away the daily sacrifice, and they shall place the abomination that maketh desolate. (Daniel 11:31)
