LXX Num 18:24

ὅτι τὰ ἐπιδέκατα τῶν υἱῶν Ἰσραὴλ ὅσα ἄν ἀφορίσωσιν κυρίῳ ἀφαίρεμα δέδωκα τοῖς Λευείταις ἐν κλήρῳ· διὰ τοῦτο εἴρηκα αὐτοῖς Ἐν μέσῳ υἱῶν Ἰσραὴλ οὐ κληρονομήσουσιν κλῆρον.

For I have given to the Levites as their inheritance the tithe that the Israelites present to the LORD as a contribution. That is why I told them that they would not receive an inheritance among the Israelites.”
