He doth execute the judgment of the fatherless and widow, and loveth the stranger, in giving him food and raiment.

Wesley's Notes

10:18 He doth execute - That is, plead their cause, and give them right against their potent adversaries, and therefore he expects you should do so too.

Matthew Henry's Concise Commentary

10:12-22 We are here taught our duty to God in our principles and our practices. We must fear the Lord our God. We must love him, and delight in communion with him. We must walk in the ways in which he has appointed us to walk. We must serve him with all our heart and soul. What we do in his service we must do cheerfully, and with good will. We must keep his commandments. There is true honour and pleasure in obedience. We must give honour to God; and to him we must cleave, as one we love and delight in, trust in, and from whom we have great expectations. We are here taught our duty to our neighbour. God's common gifts to mankind oblige us to honour all men. And those who have themselves been in distress, and have found mercy with God, should be ready to show kindness to those who are in the like distress. We are here taught our duty to ourselves. Circumcise your hearts. Cast away all corrupt affections and inclinations, which hinder you from fearing and loving God. By nature we do not love God. This is original sin, the source whence our wickedness proceeds; and the carnal mind is enmity against God, for it is not subject to the law of God, neither indeed can be; so then they that are in the flesh cannot please God, Ro 8:5-9. Let us, without delay or reserve, come and cleave to our reconciled God in Jesus Christ, that we may love, serve, and obey him acceptably, and be daily changed into his image, from glory to glory, by the Spirit of the Lord. Consider the greatness and glory of God; and his goodness and grace; these persuade us to our duty. Blessed Spirit! Oh for thy purifying, persevering, and renewing influences, that being called out of the state of strangers, such as our fathers were, we may be found among the number of the children of God, and that our lot may be among the saints.
