Tosefta for Terumot 4:6

בִּשְׁלֹשָׁה פְרָקִים מְשַׁעֲרִים אֶת הַכַּלְכָּלָה, בַּבַּכּוּרוֹת, וּבַסְּיָפוֹת, וּבְאֶמְצַע הַקָּיִץ. הַמּוֹנֶה, מְשֻׁבָּח. וְהַמּוֹדֵד, מְשֻׁבָּח מִמֶּנּוּ. וְהַשּׁוֹקֵל, מְשֻׁבָּח מִשְּׁלָשְׁתָּן:

On three occasions they measure the contents of the basket [to determine how much <i>Terumah</i> must be given]: At the time of the first ripe fruits, and of the late summer fruits, and in the middle of the summer. He who counts [the fruit] is praiseworthy, and he who measures it is more praiseworthy than him, and he who weighs them is the most praiseworthy of all three.
