5:6 Allow not thy mouth to cause thy {d} flesh to sin; neither say thou before the {e} angel, that it [was] an error: why should God be angry at thy voice, and destroy the work of thy hands?
(d) Do not cause yourself to sin by vowing rashly as they do who make a vow to live unmarried and such like.
(e) That is, before God's messenger when he will examine your doing, as though your ignorance should be a just excuse.
5:6 Thy mouth - By any rash vow. Thy flesh - Thyself, the word flesh being often put for the whole man. The angel - The priest or ministers of holy things. Such persons are often called angels, or, as this Hebrew word is commonly rendered, messengers. And this title seems to be given to the priest here, because the vow made to God, was paid to the priest as one standing and acting in God's name and stead, and it belonged to him, as God's angel or ambassador, to discharge persons from their vows when there was just occasion. It was - I did unadvisedly in making such a vow. Angry - Why wilt thou provoke God to anger at these frivolous excuses? Destroy - Blast all thy labours, and particularly that work or enterprize for the success whereof thou didst make these vows.
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.
