1 Sam 6:3

וַיֹּאמְר֗וּ אִֽם־מְשַׁלְּחִ֞ים אֶת־אֲר֨וֹן אֱלֹהֵ֤י יִשְׂרָאֵל֙ אַל־תְּשַׁלְּח֤וּ אֹתוֹ֙ רֵיקָ֔ם כִּֽי־הָשֵׁ֥ב תָּשִׁ֛יבוּ ל֖וֹ אָשָׁ֑ם אָ֤ז תֵּרָֽפְאוּ֙ וְנוֹדַ֣ע לָכֶ֔ם לָ֛מָּה לֹא־תָס֥וּר יָד֖וֹ מִכֶּֽם׃

They replied, “If you return the ark of the God of Israel, do not send it away empty, but by all means return it to Him with a guilt offering. Then you will be healed, and you will understand why His hand has not been lifted from you.”
