Ecclesiastes 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.
