The Torah specifies that Abraham profited well from deceiving Pharaoh and Avimelech by presenting Sarah as his sister:
וַיַּעַל אַבְרָם מִמִּצְרַיִם הוּא וְאִשְׁתּוֹ וְכָל־אֲשֶׁר־לוֹ וְלוֹט עִמּוֹ הַנֶּגְבָּה׃ וְאַבְרָם כָּבֵד מְאֹד בַּמִּקְנֶה בַּכֶּסֶף וּבַזָּהָב׃
From Egypt, Abram went up into the Negeb, with his wife and all that he possessed, together with Lot. Now Abram was very rich in cattle, silver, and gold.
וַיִּקַּח אֲבִימֶלֶךְ צֹאן וּבָקָר וַעֲבָדִים וּשְׁפָחֹת וַיִּתֵּן לְאַבְרָהָם וַיָּשֶׁב לוֹ אֵת שָׂרָה אִשְׁתּוֹ׃
Abimelech took sheep and oxen, and male and female slaves, and gave them to Abraham; and he restored his wife Sarah to him.
Does the Torah mention other sources of Abraham's wealth?
