Tafsiran Amsal 27:18: Rashi & Malbim

shall eat its fruit and so will one who guards his master be honored and eat the fruit of his deeds.

He who guards a fig tree will enjoy its fruit, and he who watches his master will be honored: One who wants to eat the fruit of the fig tree needs to guard it (as guarding is greater than watching). For the fruits of the fig tree ripen one by one. So he needs to pick them every morning before the sun shines. For otherwise the fruit that have ripened become wormy, as it is written in the Midrash and in the Yerushalmi. Hence one who watches his master needs to be found with him every morning and pick the fruits, meaning the fruits of his wisdom. This is as it is written about Joshua (Exodus 33:11), "he did not move from being within the tent." And through that he will be honored; he will merit the honor of [his master] placing his hands upon him (to ordain him), as said by the Sages, may their memory be blessed.
