'Ungrudgingly' in the Bible

“Tell the children of Israel to take an offering for Me. From every man whose heart moves him [to give willingly] you shall take My offering.

If any of you lacks wisdom [to guide him through a decision or circumstance], he is to ask of [our benevolent] God, who gives to everyone generously and without rebuke or blame, and it will be given to him.

Be hospitable to one another without complaint.
