5) It is true that olive-trees produce olive-shoots, and not shoots of trees other than olive-trees. Yet even olive-shoots are only non-fruitbearing olive-shoots. They are not fruit-bearing olive-trees — till they themselves later mature. Romans 11:16f cf. John 15:1-7.
6) It is incorrect to claim that infidels’ babies were killed at the exodus. Only the first-born sons of the Egyptians were — and such first-born would then usually have been adults.
7) It is incorrect to claim, in Psalm 137, that the Babylonians’ babies were to be bashed. Such babies were not criminally wicked. Those to be bashed (though called ‘little ones’), were not sucklings or toddlers but obviously adolescents or adults who had cruelly wronged Israel. The same applies to the sodomites in Sodom who had pestered Lot. Genesis 18:26-33 & 19:4-11 cf. Second Peter 2:5-8 and (Calvin’s commentary on) Jonah 4:11’s “ discern” with First Corinthians 11:28-29.
