Proverbs 30:5

Every commandment of God is fused; He is armor to those who flee to Him for protection.

The word for fused is often transalted as pure, but it has the sense of fused as the literal meaning. This conveys that every commandment of God is put in place and is unbreakable. It forms a kind of armor. Also, the pronoun translated as he could refer to the commandment rather than to God Himself. Then the commandments are the armor that those flee to for protection. Both options make sense. How do we love God? By keeping His commandments. And God works all things to the good of those who love Him. So His commandments become an armor to protect us as we flee to them for protection by obeying them out of love for Him and Him responding with protectiveness over us.
