The promise of longevity accompanies only a few of God’s commands: honoring parents (Ep 6:2-3), maintaining consistent standards in business (De 25:15), and freeing a mother bird that’s protecting her young; if we happen to find a bird’s nest we’re not allowed to take the dam, only the babies. (De 22:6-7)
Parents represent God, giving us life, protecting and guiding us, so honoring them is intuitive, and a just measure is the basis of any healthy economy. But God’s not concerned about animals per se (1Co 9:9), so why’s this third command so important?
Mothers instinctively endanger themselves to protect their own. My own dear wife Elizabeth, for example, screaming and praying for God’s mercy as a pit bull was killing our dog Hoolah, stuck her hands in its mouth to pry open its jaws, risking life and limb. My wife knows she’s infinitely more important than our dog, but in the moment she completely forgot about herself and saved Hoolah’s life. (Full story in 3rd comment below.)
Taking advantage of an animal as it tries to protect its young is a type of extortion; it’s cruel, sadistic and disrespectful. If it’s wrong to take advantage of birds in this way, how much more so of people? (1Co 6:9-10)
In promising longevity in these commands, it seems God is telling us that respecting authority, each other, and the dignity of life forms the basis of a healthy society. Cultures which follow God’s Lawtend to thrive (Ps 19:7,11); those that don’t suffer deeply. (Pr 4:19)
