Bible Verses About Birds: Mosaic law protected the mother from being taken with the young

If thou find as thou walkest by the way, a bird's nest in a tree, or on the ground, and the dam sitting upon the young or upon the eggs: thou shalt not take her with her young:

But shalt let her go, keeping the young which thou hast caught: that it may be well with thee, and thou mayst live a long time.
