Look unto Jehovah -- be strong, And He doth strengthen thy heart, Yea, look unto Jehovah!

They strengthen for themselves an evil thing, They recount of the hiding of snares, They have said, 'Who doth look at it?'

With whom My hand is established, My arm also doth strengthen him.

In the day I called, when Thou dost answer me, Thou dost strengthen me in my soul with strength.

For He did strengthen the bars of thy gates, He hath blessed thy sons in thy midst.
