3:16 And it shall come to pass, when ye are multiplied and increased in the
land, in those days, saith Jehovah, they shall say no more, The ark of the
covenant of Jehovah; neither shall it come to mind; neither shall they remember
it; neither shall they miss it; neither shall it be made any more.
Jer 3:17 At that time they shall call Jerusalem the throne of Jehovah; and all the nations shall be gathered unto it, to the name of Jehovah, to Jerusalem: neither shall they walk any more after the stubbornness of their evil heart.
Jer 3:18 In those days the house of Judah shall walk with the house of Israel, and they shall come together out of the land of the north to the land that I gave for an inheritance unto your fathers.
I find that the more you focus the Word, the more regret is forgotten and dies.
