What Am I?

Wicker, wicker, give to me
All it is you wish to give.
I will keep it, you will see,
Close to heart, long as I live.

Wicker, wicker, take from me
All it is you wish to take.
Here is where I’ll always be,
Always giving for your sake.

The fact is thus: give or take,
Know that you may surely trust
A holder, of wicker make,
To keep inside what I must.
