Numbers 26:53

לאלה תחלק הארץ TO THESE THE LAND SHALL BE DIVIDED, and not to any who are now less than twenty years old; even though they become included among those who are twenty before the division of the land, — for they were seven years in conquering it and seven years did they take in dividing it — for no one received a portion in the land except these 601,000 and if one of these had six sons, they received only their father’s portion (cf. Bava Batra 117a).

לָאֵ֗לֶּה תֵּחָלֵ֥ק הָאָ֛רֶץ בְּנַחֲלָ֖ה בְּמִסְפַּ֥ר שֵׁמֽוֹת׃

To these the land shall be divided for an inheritance according to the number of names.
