Adam Clarke on Proverbs 31:20

She stretcheth out her hand to the poor -

11. She is truly charitable. She knows that in every portion of a man's gain God requires a lot for the poor; and if this is not given, God's blessing is not in the rest. And she is not contented to give common alms. While with one hand (יד yad) she relieves the general poor, with both hands (ידיה yadeyha) she gives to the needy, לעני leaney, to the afflicted poor.
