'Obligated' in the Bible

For they were pleased to do this, and indeed they are indebted to the Jerusalem saints. For if the Gentiles have shared in their spiritual things, they are obligated also to minister to them in material things.

And I testify again to every man who lets himself be circumcised that he is obligated to obey the whole law.

and for this reason he is obligated to make sin offerings for himself as well as for the people.
