'Grudgingly' in the Bible

Therefore I considered [it] necessary to urge the brothers that they should go on ahead to you and make arrangements in advance for your generous gift that was promised previously, so this would be prepared as a generous gift and not as grudgingly granted.

Now [remember] this: he who sows sparingly will also reap sparingly, and he who sows generously [that blessings may come to others] will also reap generously [and be blessed].

Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.
