'Strengthen' in the Bible

but I have prayed [especially] for you [Peter], that your faith [and confidence in Me] may not fail; and you, once you have turned back again [to Me], strengthen and support your brothers [in the faith].”

For I long to see you so that I may share with you some spiritual gift, to strengthen and establish you;

Let each one of us [make it a practice to] please his neighbor for his good, to build him up spiritually.

Now to Him who is able to establish and strengthen you [in the faith] according to my gospel and the preaching of Jesus Christ, according to the revelation of the mystery [of the plan of salvation] which has been kept secret for long ages past,

I have sent him to you for this very purpose, so that you may know how we are, and that he may comfort and encourage and strengthen your hearts.

and so we sent Timothy, our brother and God’s servant in [spreading] the good news of Christ, to strengthen and encourage you [exhorting, comforting, and establishing you] in regard to your faith,

so that He may strengthen and establish your hearts without blame in holiness in the sight of our God and Father at the coming of our Lord Jesus with all His saints (God’s people).

Therefore encourage and comfort one another and build up one another, just as you are doing.

comfort and encourage and strengthen your hearts [keeping them steadfast and on course] in every good work and word.

But the Lord is faithful, and He will strengthen you [setting you on a firm foundation] and will protect and guard you from the evil one.

So then, strengthen hands that are weak and knees that tremble.

equip you with every good thing to carry out His will and strengthen you [making you complete and perfect as you ought to be], accomplishing in us that which is pleasing in His sight, through Jesus Christ, to whom be the glory forever and ever. Amen.

You too, be patient; strengthen your hearts [keep them energized and firmly committed to God], because the coming of the Lord is near.

After you have suffered for a little while, the God of all grace [who imparts His blessing and favor], who called you to His own eternal glory in Christ, will Himself complete, confirm, strengthen, and establish you [making you what you ought to be].

Therefore, believers, be all the more diligent to make certain about His calling and choosing you [be sure that your behavior reflects and confirms your relationship with God]; for by doing these things [actively developing these virtues], you will never stumble [in your spiritual growth and will live a life that leads others away from sin];

Wake up, and strengthen and reaffirm what remains [of your faithful commitment to Me], which is about to die; for I have not found [any of] your deeds completed in the sight of My God or meeting His requirements.
