Arad, Early 7th century BCE
Written by a professional scribe in ink on a potsherd in ancient Hebrew script-
“To my lord Eliashib, may the Lord seek your welfare and now- Give to Shemaryahu a lethech and to the Kerosi give a homer(probably volume measurements), and as to the matter which you commanded me—it is well; he is in the House of God.”
