Drink water from your own well and love only your wife. Men be careful of who you speak to or confide in especially when it is someone who is not your wife. Don’t open yourself up towards feelings confiding in the opposite sex that could cause division in your marriage.
God says “Drink water from your own cistern,
running water from your own well.
Should your springs overflow in the streets,
your streams of water in the public squares?
Let them be yours alone,
never to be shared with strangers.
May your fountain be blessed,
and may you rejoice in the wife of your youth.”
