Give not sleep to thine eyes, nor slumber to thine eyelids.
– Proverbs 6:4
[T]he point Solomon presses is urgency in freeing oneself from so unwise and potentially disastrous of a decision. The urgency throughout this section of verses reflects the serious nature of the problem. The point is to take it seriously and not casually and to do all that can be done in honesty to get out of the obligation, including humbling yourself extremely.
