(Pro 30:15 KJV) The horseleach hath two daughters, crying, Give, give. There are three things that are never satisfied, yea, four things say not, It is enough:
The KJV translates this with “horseleach” (5936). When I looked for a definition I came up with, “a large leech, as Haemopis marmoratis, that infests the mouth and nasal passages of horses.” I asked myself how a horse could pick up such parasites. To my knowledge leaches live in water. I would imagine that a leech could attach when the horse was drinking infested water.
So heed the warning. Be careful where you drink. Take that figuratively or metaphorically. We seek knowledge and companionship in varied ways. Some are neutral, some beneficial and some are evil. The evil will infest your mind and soul. It will suck the joy and possibly the salvation out of you.
So? Feed on God’s word. Keep your eyes open. I remember getting in a lake in the Midwest, seeing leeches in the water and immediately exiting.
