The Hebrew noun aggartal (אֲגַרְטָל) refers to a basin or broad, shallow bowl — likely a Persian loanword — used for holding liquids. It appears in the inventory of temple vessels returned from Babylon.
The temple vessels carried enormous theological weight. Their looting by Nebuchadnezzar signified judgment; their return under Cyrus (Ezra 1:9–11) signified restoration. God's faithfulness to His covenant was made tangible in the return of these sacred objects, foreshadowing the greater restoration through Christ in whom all things are recapitulated.
