15 “Drink water from your own cistern,
flowing water from your own well”
OR don’t mow someone else’s grass Or The grass isn’t always greener on the other side of the fence. Whatever you wanna call it .. and however you want to say it …when your in a covenant with marriage between your spouse and the Lord you should just keep to each other – no wandering eyes – no wandering hands – guard your thoughts – protect your morals and keep with each other.
Maybe they use the words drink water from your own well was used because in the desert water is precious as the gift of love from God is, and if you were to go to steal from someone’s well – that was frowned upon. I further did some research to realize the immoral woman in v3 is referring to a prostitute. One can buy sex but you can’t buy happiness… you can’t buy pure true joy. Doing that whether you are married or not reduces the value of the gift of love that God gives us, It degrades humanity and destroys family life and can lead to no good.
