Sirach 35: 12 - 14, 16 - 18
12 Do not offer him a bribe, for he will not accept it; and do not trust to an unrighteous sacrifice; for the Lord is the judge, and with him is no partiality.
13 He will not show partiality in the case of a poor man; and he will listen to the prayer of one who is wronged.
14 He will not ignore the supplication of the fatherless, nor the widow when she pours out her story.
16 He whose service is pleasing to the Lord will be accepted, and his prayer will reach to the clouds.
17 The prayer of the humble pierces the clouds, and he will not be consoled until it reaches the Lord; he will not desist until the Most High visits him, and does justice for the righteous, and executes judgment.
18 And the Lord will not delay, neither will he be patient with them, till he crushes the loins of the unmerciful and repays vengeance on the nations; till he takes away the multitude of the insolent, and breaks the scepters of the unrighteous;
