1 Chronicles 22:13

Then will he prosper [thee], if thou take heed to do the commandments and judgments which the Lord commanded Moses for Israel: be courageous and strong; fear not, nor be terrified.

Then shalt thou prosper, if thou takest heed to fulfil the statutes and judgments which the Lord charged Moses with concerning Israel: be strong, and of good courage; dread not, nor be dismayed.

Then you will prosper, if you observe to do the statutes and the ordinances which Yahweh gave Moses concerning Israel. Be strong and courageous. Don’t be afraid and don’t be dismayed.
