'Tree of Life' in the Bible

She is a tree of life to those who take hold of her,And happy [blessed, considered fortunate, to be admired] is everyone who holds her tightly.

The fruit of the [consistently] righteous is a tree of life,And he who is wise captures and wins souls [for God—he gathers them for eternity].

Hope deferred makes the heart sick,But when desire is fulfilled, it is a tree of life.

A soothing tongue [speaking words that build up and encourage] is a tree of life,But a perversive tongue [speaking words that overwhelm and depress] crushes the spirit.
