How many times does the word Palestine appear in the Bible?

Les explains that the word Palestine is found in Scripture only once, yet it is indeed there, referring to the land of Palestine. He notes that the Palestinian covenant is one of the covenants under the Abrahamic covenant, named because it pertains to the land of Palestine. He uses the term for geographical clarity, since everyone knows where Palestine is. He also points out that Christ's earthly ministry was confined to Israel, with only two exceptions, as seen in Matthew 10 and 15.
