'Firm' in the Bible

You will protect a firm inclination [in] peace, [in] peace because he trusts in you.

Your riggings hang slack; they do not hold the base of their mast firm, they do not spread out [the] sail. Then [the] prey of spoil [in] abundance will be divided; [the] lame will take plunder.

Strengthen [the] weak hands and make [the] staggering knees firm.

They do not know [the] way of peace, and there is no justice in their firm paths. They have made their paths crooked for themselves; everyone {who walks} in it knows no peace.
