Sirach 35:6-16

6 The offering of the righteous maketh the altar fat, and the sweet savour thereof is before the most High.
7 The sacrifice of a just man is acceptable. and the memorial thereof shall never be forgotten.
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.
13 He will not accept any person against a poor man, but will hear the prayer of the oppressed.
14 He will not despise the supplication of the fatherless; nor the widow, when she poureth out her complaint.
15 Do not the tears run down the widow's cheeks? and is not her cry against him that causeth them to fall?
16 He that serveth the Lord shall be accepted with favour, and his prayer shall reach unto the clouds.
