As for me, this [is] my covenant with them, saith the LORD; My spirit that [is] upon thee, and my words which I have put in thy mouth, shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seed’s seed, saith the LORD, from henceforth and for ever.
Berean Study Bible (BSB) - Isaiah 59:21 >“As for Me, this is My covenant with them,” says the LORD. “My Spirit will not depart from you, and My words that I have put in your mouth will not depart from your mouth or from the mouths of your children and grandchildren, from now on and forevermore,” says the LORD.
