Exodus 35:21-29
21 And they came, every one whose heart stirred him up, and every one whom his spirit made willing, and they brought the Lord‘s offering to the work of the tabernacle of the congregation, and for all his service, and for the holy garments.
22 And they came, both men and women, as many as were willing hearted, and brought bracelets, and earrings, and rings, and tablets, all jewels of gold: and every man that offered offered an offering of gold unto the Lord. (KJV)
2 Corinthians 9:1-15
6 But this I say, He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully.
7 Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver. (KJV)
