There are actually two primary definitions, hence why I asked:
to receive as return for effort and especially for work done or services rendered // to bring in by way of return
to come to be duly worthy of or entitled or suited to // to make worthy of or obtain for
Every major dictionary has some variation on both of these, including whatever duckduckgo uses
Edit, I looked up your reference and I find it interesting you chose the third definition listed by duckduckgo to highlight here. But my point stands and both are there. The other definition is derivative of the third.
