Deuteronomy 11:8

Be strong and of a good courage: for unto this people shalt thou divide for an inheritance the land, which I sware unto their fathers to give them. Only be thou strong and very courageous, that thou mayest observe to do according to all the law, which Moses my servant commanded thee: turn not from it to the right hand or to the left, that thou mayest prosper whithersoever thou goest.

Finally, my brethren, be strong in the Lord, and in the power of his might.

And he gave Joshua the son of Nun a charge, and said, Be strong and of a good courage: for thou shalt bring the children of Israel into the land which I sware unto them: and I will be with thee.

That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man;

I can do all things through Christ which strengtheneth me.

And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ’s sake: for when I am weak, then am I strong.

When thou hast eaten and art full, then thou shalt bless the Lord thy God for the good land which he hath given thee. Beware that thou forget not the Lord thy God, in not keeping his commandments, and his judgments, and his statutes, which I command thee this day:

In the day when I cried thou answeredst me, and strengthenedst me with strength in my soul.

Strengthened with all might, according to his glorious power, unto all patience and longsuffering with joyfulness;

And said, O man greatly beloved, fear not: peace be unto thee, be strong, yea, be strong. And when he had spoken unto me, I was strengthened, and said, Let my lord speak; for thou hast strengthened me.

And now, Israel, what doth the Lord thy God require of thee, but to fear the Lord thy God, to walk in all his ways, and to love him, and to serve the Lord thy God with all thy heart and with all thy soul, To keep the commandments of the Lord, and his statutes, which I command thee this day for thy good? Behold, the heaven and the heaven of heavens is the Lord’s thy God, the earth also, with all that therein is. Only the Lord had a delight in thy fathers to love them, and he chose their seed after them, even you above all people, as it is this day.

This day the Lord thy God hath commanded thee to do these statutes and judgments: thou shalt therefore keep and do them with all thine heart, and with all thy soul. Thou hast avouched the Lord this day to be thy God, and to walk in his ways, and to keep his statutes, and his commandments, and his judgments, and to hearken unto his voice: And the Lord hath avouched thee this day to be his peculiar people, as he hath promised thee, and that thou shouldest keep all his commandments; And to make thee high above all nations which he hath made, in praise, and in name, and in honour; and that thou mayest be an holy people unto the Lord thy God, as he hath spoken.

Because thou servedst not the Lord thy God with joyfulness, and with gladness of heart, for the abundance of all things;

Be strong and of a good courage, fear not, nor be afraid of them: for the Lord thy God, he it is that doth go with thee; he will not fail thee, nor forsake thee. And Moses called unto Joshua, and said unto him in the sight of all Israel, Be strong and of a good courage: for thou must go with this people unto the land which the Lord hath sworn unto their fathers to give them; and thou shalt cause them to inherit it.

What shall I render unto the Lord for all his benefits toward me? I will take the cup of salvation, and call upon the name of the Lord. I will pay my vows unto the Lord now in the presence of all his people. Precious in the sight of the Lord is the death of his saints. O Lord, truly I am thy servant; I am thy servant, and the son of thine handmaid: thou hast loosed my bonds.

But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.
