The tree of life shall give them fragrant perfume means this tree will give a fragrant smell to God’s new people. The tree of life enables the people who eat its fruit to live forever (see Gen 2.9; 3.22; Rev 2.7; 22.2; 2 Esd 8.52). This phrase may be translated “the tree that gives life” (Contemporary English Version) or “the tree whose fruit causes people to live forever.”

And they shall neither toil nor become weary means they will never have to work, nor will they ever become tired.

The following model of this verse is based on Contemporary English Version:

• My people will smell the sweet fragrance of the tree that gives life, and they will no longer [have to] work or become tired.
