Sirach 35:10 In-Context

8 Give the Lord his honour with a good eye, and diminish not the firstfruits of thine hands.
9 In all thy gifts shew a cheerful countenance, and dedicate thy tithes with gladness.
10 Give unto the most High according as he hath enriched thee; and as thou hast gotten, give with a cheerful eye.
11 For the Lord recompenseth, and will give thee seven times as much.
12 Do not think to corrupt with gifts; for such he will not receive: and trust not to unrighteous sacrifices; for the Lord is judge, and with him is no respect of persons.
