For many years, I thought this verse meant if we just kind of sit and wait patiently, without striving, God would renew our strength to help us get through those tough times when we are worn down to nothing.
The word wait, qavah, means to bind together by twisting. When we bind ourselves together with the Lord by twisting, He renews our strength. Renew written in the tense it is written, the Hiphil Imperfect, means that God will exchange our strength for His. It is through the binding together that this happens.
BIND US TOGETHER, Lord, Bind us together
With cords that cannot be broken.
Bind us together, Lord,
Bind us together,
Bind us together with love.
