Matthew Poole's Concise Commentary
Ecclesiastes 5:6
Suffer not thy mouth, by uttering any rash or foolish vow. Thy flesh, i. e. thyself, the word flesh being oft put for the whole man, as Genesis 6:12 Isaiah 40:5 Romans 3:20, &c. And it seems to have some emphasis here, and to intimate either,
1. That such vows were made upon fleshly or carnal, and not upon spiritual and religious motives. Or rather,
2. That the flesh or corrupt nature of man, which is oft called flesh, was exceeding prone to set itself at ease and liberty from such bonds, and to neglect the chargeable duties of religion. The angel; either,
1. The blessed angels, the singular number being put for the plural, who are present in the public assemblies in which these vows were generally paid, Psalms 66:13, where they observe both the matter and manner of men's religious performances, as appears from 1 Corinthians 11:10, who as they rejoice in the conversion of a sinner, Luke 15:10, so are displeased with the sins of men, and especially such as are committed in or against the worship of God. Or,
2. Christ, who in the Old Testament is frequently called an angel, as hath been oft noted before, and the Angel of the covenant, Zechariah 3:1 because even then he acted as God's messenger, appearing and speaking to the patriarchs and prophets in his Father's name, as a prosignification of his future incarnation, and who is and was in a special manner present in all religious assemblies; and being omniscient and omnipresent, exactly knew and observed all the vows which men made, and whether they did perform or violate them. Or rather,
3. The priest or minister of holy things, who was to require of the people the payment of their vows, to whom all sacrifices for sins of ignorance or errors about vows or other things were to be brought, Leviticus 5:4,5. For such persons are oft called angels, or, as this Hebrew word is commonly rendered, messengers, as Job 33:23 Zechariah 2:7 Revelation 1:20. And this title seems to be given to the priest here, not without some emphasis, 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 the priest, as God's angel or ambassador, to discharge persons from their vows when there was just occasion so to do. That it was an error; I did foolishly and unadvisedly in making such a vow, and therefore I hope God will excuse me, and instead of that which I had vowed, accept of a sacrifice for my ignorance, according to the law for sins of ignorance, Leviticus 4:2, Leviticus 5:15 Numbers 15:26. Wherefore should God be angry, why wilt thou provoke God to anger, at thy voice? either,
1. At the vows which thou hast hastily uttered with thy mouth, as he said above. Or rather,
2. At these frivolous excuses, wherewith thou deludest thy own conscience, and vainly imaginest that thou canst deceive God himself. Destroy the work of thine hands; blast all thy contrivances, and labours, and estate gotten by thy labours, and particularly that work or enterprise for the success whereof thou didst make these vows, which being, as thou thinkest, finished, thou refusest to pay thy vows; but know that God can quickly undo that which thou hast done, and plentifully repay thine indignities and injuries offered to him into thine own bosom.
