What does Psalm 10:10 mean?

Just as a vicious lion pounces on his victim and crushes its bones until it collapses and dies, even so the wicked person overpowers his helpless victim and kills him (Psalm 10:9). Use of force against those who are weak and helpless is a hallmark of wickedness and evil (Psalm 10:2–3).

Because he feared the growing population of the Hebrew slaves, the powerful pharaoh of Egypt summoned the full force of his empire to kill the helpless male Hebrew babies. He commanded the midwives: "When you serve as a midwife to the Hebrew women and see them on the birthstool, if it is a son, you shall kill him, but if it is a daughter, she shall live" (Exodus 1:16). Centuries later, in an effort to kill Baby Jesus, King Herod "sent and killed all the male children in Bethlehem and in all that region who were two years old or under, according to the time that he had ascertained from the wise men" (Matthew 2:16).
