Genesis 13:6

ולא נשא אתם AND THE LAND WAS NOT ABLE TO BEAR THEM — It could not provide sufficient pasture for their cattle. The phrase is elliptical and a word must be supplied, for instance: the pasturage (מרעה) of the land was not able to bear them — for this reason the word נשא (masculine) is used (to agree in gender with מרעה; the suggestion is that נשא cannot have הארץ as subject since that noun is feminine).

וְלֹא־נָשָׂ֥א אֹתָ֛ם הָאָ֖רֶץ לָשֶׁ֣בֶת יַחְדָּ֑ו כִּֽי־הָיָ֤ה רְכוּשָׁם֙ רָ֔ב וְלֹ֥א יָֽכְל֖וּ לָשֶׁ֥בֶת יַחְדָּֽו׃

And the land was not able to bear them, that they might dwell together: for their substance was great, so that they could not dwell together.
