Deuteronomy 22:6

Since by this precept God instructed His people in the, law of kindness, it is a Supplement to the Sixth Commandment. Regard was had, indeed, to the preservation of the breed; but, besides, when birds are sitting, as being very lean, it is certain that they are not wholesome food; still there is no question but that it was God’s intention to accustom His people to study humanity. For, if there be one drop of compassion in us, it will never enter into our minds to kill an unhappy little bird, which so burns either with the desire of offspring, or with love towards its little ones, as to be heedless of its life, and to prefer endangering itself to the desertion of its eggs, or its brood. Wherefore, it is not to be doubted but that in this elementary lesson, God prohibited His people from savageness and cruelty.
