5:4-8 When a person made engagements rashly, he suffered his mouth to cause his flesh to sin. The case supposes a man coming to the priest, and pretending that his vow was made rashly, and that it would be wrong to fulfil it. Such mockery of God would bring the Divine displeasure, which might blast what was thus unduly kept. We are to keep down the fear of man. Set God before thee; then, if thou seest the oppression of the poor, thou wilt not find fault with Divine Providence; nor think the worse of the institution of magistracy, when thou seest the ends of it thus perverted; nor of religion, when thou seest it will not secure men from suffering wrong. But though oppressors may be secure, God will reckon for all.
6. thy flesh—Vow not with "thy mouth" a vow (for example, fasting), which the lusts of the flesh ("body," Ec 2:3, Margin) may tempt thee to break (Pr 20:25).
angel—the "messenger" of God (Job 33:23); minister (Re 1:20); that is, the priest (Mal 2:7) "before" whom a breach of a vow was to be confessed (Le 5:4, 5). We, Christians, in our vows (for example, at baptism, the Lord's Supper, &c.) vow in the presence of Jesus Christ, "the angel of the covenant" (Mal 3:1), and of ministering angels as witnesses (1Co 11:10; 1Ti 5:21). Extenuate not any breach of them as a slight error.
