הבא בידו. בִּרְשׁוּתוֹ, וְכֵן וַיִּקַּח אֶת כָּל אַרְצוֹ מִיָּדוֹ (במדבר כ"א). וּמִ"אַ מִן הַבָּא בְיָדוֹ – אֲבָנִים טוֹבוֹת וּמַרְגָלִיּוֹת, שֶׁאָדָם צָר בִּצְרוֹר וְנוֹשְׂאָם בְּיָדוֹ (דָּ"אַ מִן הַבָּא בְיָדוֹ, מִן הַחֻלִּין, שֶׁנָּטַל מַעֲשֵׂר, כְּמָה דְּאַתְּ אָמַר עַשֵּׂר אֲעַשְּׂרֶנּוּ לָךְ, וַהֲדַר לָקַח מִנְחָה):
הבא בידו AND TOOK OF THAT WHICH CAME TO HIS HAND (literally, in his hand) — in his possession, similar to (Numbers 21:26) “and he had taken all his land out of his possession (מידו).” A Midrashic explanation is: מן הבא בידו — precious stones and jewels which a person ties up in a package and carries in his hand. Another explanation is: מן הבא בידו THAT WHICH A MAN MAY TAKE INTO HIS OWN POSSESSION — of that which no longer has a sacred character — for he had set aside the tithe, just as you read (28:22) “[And Jacob vowed] … I will surely give the tenth unto Thee”. Only afterwards did he take the present of what was left after the tithe had been set aside, and this was that which he might rightly take into his own possession.
