Parallel
Deuteronomy 21:17
Clementine Vulgate · Berean Standard Bible
sed filium odiosæ agnoscet primogenitum, dabitque ei de his quæ habuerit cuncta duplicia : iste est enim principium liberorum ejus, et huic debentur primogenita.
Instead, he must acknowledge the firstborn, the son of his unloved wife, by giving him a double portion of all that he has. For that son is the firstfruits of his father’s strength; the right of the firstborn belongs to him.
