King James Version (KJV) - Isaiah 48:7 >They are created now, and not from the beginning; even before the day when thou heardest them not; lest thou shouldest say, Behold, I knew them.
Berean Study Bible (BSB) - Isaiah 48:7 >They are created now, and not long ago; you have not heard of them before today. So you cannot claim, ‘I already knew them!’
