Whoso stoppeth his ears - See the conduct of the priest and Levite to the man who fell among thieves; and let every man learn from this, that he who shuts his ear against the cry of the poor, shall have the ear of God shut against his cry. The words are quite plain; there is no difficulty here.

Whoso stoppeth his ears at the cry of the poor,.... For want of bread; or, "of the weak", as the Septuagint and other versions; for want of help and protection, when in the greatest distress; and, with the most pressing importunity, entreats his assistance, and yet refuses to hear him out: or, if he does, will not relieve him, which is all one as if he heard him not, or denied him a hearing;
he also shall cry himself; the Targum and Syriac version add, "unto God". The sense is, that even such an one shall be brought into the like distressed circumstances, when he shall make application to God, and to his fellow creatures, for relief and assistance:
but shall not be heard; a deaf ear will be turned to him by both: the same measure he has measured shall be measured to him again; no mercy shall be shown to an unmerciful man, either by God or man; see James 2:13.

Such as oppress the poor by beating down wages, such as will not relieve according to their ability those in distress, and those in authority who neglect to do justice, stop their ears at the cry of the poor. But doubtless care is to be used in the exercise of charity.

The principles of retribution, often taught (compare Psalm 18:26; Matthew 7:1-12).

13 He that stoppeth his ear at the cry of the poor
he also calls and is not heard.
Only the merciful find mercy, Matthew 5:7; the unmerciful rich man, who has no ear for the cry of the דל, i.e., of him who is without support and means of subsistence, thus of one who is needing support, will also remain unheard when he himself, in the time of need, calls upon God for help. Cf. the parable of the unmerciful servant of the merciful king, Matthew 18:23. מן in מזּעקת, as Isaiah 23:15; Genesis 4:13; Genesis 27:1; no preposition of our [German] language [nor English] expresses, as Fleischer here remarks, such a fulness of meaning as this מן does, to which, after a verb of shutting up such as אטם (cf. Proverbs 17:28), the Arab. 'n would correspond, e.g., â'my 'n âltryḳ: blind, so that he does not see the way.
