פירוש על בראשית 31:18

מקנה קנינו means — what he had purchased by means of קנינו his own property i.e. his sheep, viz., menservants, maidservants, camels and asses (Genesis Rabbah 74:5; cf. Rashi on Genesis 30:43).

וינהג...מקנה קנינו, the first time the word מקנהו appears in our verse it refers to cattle Yaakov had acquired as a result of his activities as shepherd. The expression מקנה קנינו on the other hand, refers to livestock he had purchased. Whenever the word מקנה is spelled with the vowel tzeyreh under the letter נ this indicates that it is in the construct mode.

All his possessions. He did not exchange his livestock for more easily transported currency. To come to Yitzchok. He acknowledged openly to Lavan’s household that he was leaving, so they assumed that he had Lavan’s permission and did not bother reporting it.
