You can often find this Scripture passage in relation to Stephen Ministry efforts (for example, click on the illustration or this link).
Like the old song goes...
Lean on me when you're not strong,
and I'll be your friend,
I'll help you carry on;
For it won't be long 'til I'm gonna need
somebody to lean on.
