Matthew Poole and continuators on Deuteronomy 22:7

7 But thou shalt in any wise let the dam go , and take the young to thee, that it may be well with thee, and that thou mayest prolong thy dayes.

Partly for the Birds sake, which suffered enough by the loss of its young; for God would not have cruelty exercised towards the brute Creatures: and partly for mens sake to restrain their greediness and covetousness that they should not monopolize all to themselves, but might leave the hopes of a future seed for others.
