The Talmud discusses why a thief (ganav) pays double restitution while a robber (gazlan) pays only the principal, concluding that the thief's fear of humans exceeding his fear of God makes his offense graver in some respects — a foundational distinction in gezel law.
שָׁאֲלוּ תַּלְמִידָיו אֶת רַבָּן יוֹחָנָן בֶּן זַכַּאי: מִפְּנֵי מָה הֶחְמִירָה תּוֹרָה בְּגַנָּב יוֹתֵר מִגַּזְלָן? אָמַר לָהֶן: זֶה – הִשְׁוָה כְּבוֹד עֶבֶד לִכְבוֹד קוֹנוֹ, וְזֶה – לֹא הִשְׁוָה כְּבוֹד עֶבֶד לִכְבוֹד קוֹנוֹ. כִּבְיָכוֹל עָשָׂה עַיִן שֶׁל מַטָּה כְּאִילּוּ אֵינָהּ רוֹאָה, וְאוֹזֶן שֶׁל מַטָּה כְּאִילּוּ אֵינָהּ שׁוֹמַעַת, שֶׁנֶּאֱמַר: ״הוֹי הַמַּעֲמִיקִים מֵה׳ לַסְתִּר עֵצָה, וְהָיָה בְמַחְשָׁךְ מַעֲשֵׂיהֶם וְגוֹ׳״; וּכְתִיב: ״וַיֹּאמְרוּ לֹא יִרְאֶה יָּהּ וְלֹא יָבִין אֱלֹהֵי יַעֲקֹב״; וּכְתִיב: ״כִּי [אָמְרוּ] עָזַב ה׳ אֶת הָאָרֶץ, וְאֵין ה׳ רֹאֶה״. תַּנְיָא, אָמַר רַבִּי מֵאִיר: מָשְׁלוּ מָשָׁל מִשּׁוּם רַבָּן גַּמְלִיאֵל, לְמָה הַדָּבָר דּוֹמֶה? לִשְׁנֵי בְּנֵי אָדָם שֶׁהָיוּ בְּעִיר וְעָשׂוּ מִשְׁתֶּה, אֶחָד זִימֵּן אֶת בְּנֵי הָעִיר וְלֹא זִימֵּן אֶת בְּנֵי הַמֶּלֶךְ, וְאֶחָד לֹא זִימֵּן אֶת בְּנֵי הָעִיר וְלֹא זִימֵּן אֶת בְּנֵי הַמֶּלֶךְ. אֵיזֶה מֵהֶן עוֹנְשׁוֹ מְרוּבֶּה? הֱוֵי אוֹמֵר: זֶה שֶׁזִּימֵּן אֶת בְּנֵי הָעִיר וְלֹא זִימֵּן אֶת בְּנֵי הַמֶּלֶךְ.
§ The Gemara concludes its discussion of theft with several aggadic statements. His students asked Rabban Yoḥanan ben Zakkai: For what reason was the Torah stricter with a thief than with a robber? Only a thief is required to pay the double, fourfold, or fivefold payment, not a robber. Rabban Yoḥanan ben Zakkai said to them in response: This one, the robber, equated the honor of the servant to the honor of his Master, and that one, the thief, did not equate the honor of the servant to the honor of his Master. The robber fears neither God nor people, as he is not afraid to rob in public. The thief does not fear God but he does fear other people, which demonstrates that he is more concerned about humans than God. As it were, the thief establishes the eye below, i.e., God’s eye, as though it does not see, and the ear below, i.e., God’s ear, as though it does not hear. The Gemara cites verses that describe people who imagine that God does not see their actions, as it is stated: “Woe to them who seek deeply to hide their counsel from the Lord, and their works are in the dark, and they say: Who sees us, and who knows us?” (Isaiah 29:15). And it is written: “And they say: The Lord will not see, neither will the God of Jacob give heed” (Psalms 94:7). And it is written: “For they say: The Lord has forsaken the land, and the Lord does not see” (Ezekiel 9:9). It is taught in a baraita that Rabbi Meir said: To illustrate the severity of a thief over a robber, as per Rabban Yoḥanan ben Zakkai’s explanation, they stated a parable in the name of Rabban Gamliel. To what is this matter comparable? To two people who were living in the same city, and both of them prepared a feast. One of them invited the people of the city to his feast but he did not invite the king’s sons. And the other did not invite the people of the city and also did not invite the king’s sons. Which of them deserves a greater punishment? You must say that it is this one who invited the people of the city but did not invite the king’s sons. Likewise, both the thief and the robber show disdain for God, but the robber does not display more respect for people.
