They are created now, and not from of old; and before this day thou heardest them not; lest thou shouldest say, Behold, I knew them.

They are created now, and not long ago; you have not heard of them before today. So you cannot claim, ‘I already knew them!’

Now they have been produced and not from that time, Yea, before the day, and thou hast not heard them, Lest thou say, `Lo, I have known them.'

they are created now, and not long ago; and before this day thou hast not heard them, lest thou shouldest say, Behold, I knew them.
