In Job 1:5, it is written,

And it was so, when the days of their feasting were gone about, that Job sent and sanctified them, and rose up early in the morning, and offered burnt offerings according to the number of them all: for Job said, It may be that my sons have sinned, and cursed God in their hearts. Thus did Job continually. (King James Version, 1769)

וַיְהִי כִּי הִקִּיפוּ יְמֵי הַמִּשְׁתֶּה וַיִּשְׁלַח אִיּוֹב וַיְקַדְּשֵׁם וְהִשְׁכִּים בַּבֹּקֶר וְהֶעֱלָה עֹלוֹת מִסְפַּר כֻּלָּם כִּי אָמַר אִיּוֹב אוּלַי חָטְאוּ בָנַי וּבֵרְכוּ אֱלֹהִים בִּלְבָבָם כָּכָה יַעֲשֶׂה אִיּוֹב כָּל הַיָּמִים (Mechon-Mamre)

Does Job offer sacrifices to atone for the sins of others, i.e. his sons?
