Scripture does not mince words.
People are called swine and vipers. Heathen, fools and dogs are used many times. Christ himself called a Canaanite woman’s child a little dog thus implying that she was a dog, which she accepted.
There is always a lesson to be learned from scripture. Being wise as a serpent while gentle as doves includes the ability to discriminate between your neighbor and an enemy. The misused phrase “All men are created equal” is in the Declaration of the Constitution, not scripture. Equality is found only under Christ. It is an impossible goal any where else.
Read Romans 9:1-23
Unfortunately even your neighbor can sometimes behave poorly.
Matthew 7:6 “Don’t give that which is holy to the dogs, neither throw your pearls before the pigs, lest perhaps they trample them under their feet, and turn and tear you to pieces.
Matthew 7:6 is not being taught for all that it means.
