A deliberate verbal borrowing without a citation formula.
The Corban dispute turns on the binding force of a vow dedicating property to God; Numbers 30 is the Torah's law of vows ('he shall not break his word, he shall do according to all that proceeds out of his mouth'). Jesus' charge is that scribal handling of such irrevocable vows is used to override the prior duty to parents, so the vow legislation is the legal substrate of the controversy. Thematic coherence high; verbal volume moderate.
Medium confidenceLaw of vows: 'If a man vows a vow to the LORD... he shall not break his word.' Underlies the Corban ('a gift devoted to God') practice Jesus targets — a binding vow weaponized against the fifth commandment.
