'Strengthen' in the Bible

Immediately the father cried out, "I do believe: strengthen my weak faith."

But *I* have prayed for *you* that your faith may not fail, and you, when at last you have come back to your true self, must strengthen your brethren."

In conclusion, strengthen yourselves in the Lord and in the power which His supreme might imparts.

Therefore encourage one another, and let each one help to strengthen his friend, as in fact you do.

Therefore strengthen the drooping hands and paralysed knees,

Rouse yourself and keep awake, and strengthen those things which remain but have well-nigh perished; for I have found no doings of yours free from imperfection in the sight of My God.
