Bring forth therefore fruits worthy of repentance,.... Or "meet" for it, such as will show it to be true and genuine: "and begin not to say within yourselves": in one of Beza's copies, and in another of Stephens's, it was read, "think not", as in Mat 3:9. the sense is the same. The Vulgate Latin and Ethiopic versions, leave out the phrase, "within yourselves": what they are forbid to say follows, we have Abraham to our father, for I say unto you, God is able of these stones to raise up children unto Abraham; which need not be thought strange, when the creation of Adam out of the earth, and the production of such a numerous offspring, as the Israelites were, from Abraham and Sarah, when past all hope of children, and are signified by the rock and pit in Isa 51:1 are considered; See Gill on Mat 3:9.
