'Be Strong' in the Bible

And he saith, 'If Aram be stronger than I, then thou hast been to me for salvation; and if the sons of Ammon be stronger than thou, then I have saved thee;

be strong, and we strengthen ourselves, for our people, and for the cities of our God, and Jehovah doth that which is good in His eyes.'

then thou dost prosper, if thou dost observe to do the statutes and the judgments that Jehovah charged Moses with concerning Israel; be strong and courageous; do not fear, nor be cast down.

See, now, for Jehovah hath fixed on thee to build a house for a sanctuary; be strong, and do.'

And David saith to Solomon his son, 'Be strong, and courageous, and do; do not fear nor be affrighted, for Jehovah God, my God, is with thee; He doth not fail thee, nor forsake thee, unto the completion of all the work of the service of the house of Jehovah.
