In other words, there's another teaching on divorce here, both of which forbid--it also forbids divorce and remarriage, but it's not the same wording as in Mark, so scholars say, that looks like a Q saying on divorce in which Jesus still forbids divorce and remarriage but it's not the same wording as the Mark saying, so we have two separate sayings and different wordings, but they both have Jesus forbidding divorce, at least divorce and remarriage; one in Q, one in Mark, two independent sources.
