'Tablet' in the Bible

Never let loyalty and faithfulness leave you.Tie them around your neck;write them on the tablet of your heart.

Tie them to your fingers;write them on the tablet of your heart.

Go now, write it on a tablet in their presenceand inscribe it on a scroll;it will be for the future,forever and ever.

The sin of Judah is writtenwith an iron stylus.With a diamond pointit is engraved on the tablet of their heartsand on the horns of their altars,
