'Prosper' in the Bible

But a spirit empowered Amasai, the leader of the thirty warriors, and he said: "We are yours, O David! We support you, O son of Jesse! May you greatly prosper! May those who help you prosper! Indeed your God helps you!" So David accepted them and made them leaders of raiding bands.

Now, my son, the LORD be with thee; and prosper thou, and build the house of the LORD thy God, as he hath said of thee.

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.
