The story of Jethro, Moses' father-in-law, offers a fascinating glimpse. Jethro, who according to the tradition, excelled all other converts in his love for the Torah, wasn’t just welcomed into the Israelite camp; he was showered with miracles.

The Midrash tells us that on the very day Jethro arrived, manna—that miraculous bread from heaven—fell in abundance, specifically for him, at the very hour of his arrival. The amount? Enough for sixty myriads of Israelites! It's said he didn't even have to exert himself; the manna simply fell right over him, ready to be eaten. Now, that’s hospitality!

But here's where the story takes an unexpected turn. Despite this miraculous welcome, Jethro decided to return to his homeland. Why? What could possibly compel someone to leave such a privileged position?

Moses, naturally, tried to persuade him to stay. According to Ginzberg's retelling in Legends of the Jews, Moses even hinted that their journey through the desert would soon be over, implying Jethro would enter the Promised Land with them. Moses sweetened the deal, promising Jethro that they would be kinder to him than to all other proselytes.

But Jethro remained firm. He felt obligated to return. The reason? He was a trusted figure in his community. People had entrusted him with their valuables. If he stayed away too long, they might suspect him of running off with their possessions, tarnishing his good name and, by association, Moses' too. It was also said he had debts from helping the poor during a famine and didn't want to appear to be evading his creditors, which would be a hillul Hashem, a desecration of God's name.

Jethro poignantly explained, "There are people who have a fatherland, but no property there; there are also property-holders who have no family; but I have a fatherland, and have property there as well as a family; hence I desire to return to my fatherland, my property, and my family."

Moses, not willing to give up easily, then appealed to Jethro's sense of duty. He argued that if Jethro left, the Israelites might be accused of only accepting converts in the hope of gaining land, and the heathens would keep away from the true faith. If he stayed, Jethro would share in the Temple, the Torah, and the future reward of the pious. Moses even suggested Jethro stay to serve as a member of the Sanhedrin, the Jewish high court, and to teach the Torah.

Jethro countered with a beautiful metaphor: "A candle may glow in the dark, but not when the sun and the moon are shining; of what avail would my candle-light be?" He believed he could be more effective back home, converting his people and bringing them "under the wings of the Shekinah" — the Divine Presence.

In the end, Jethro returned home, laden with gifts and honors. And, true to his word, he converted his kinsmen and compatriots to the belief in the one true God.

So, what do we take away from Jethro's story? It's a reminder that piety isn't just about personal gain or even staying within a comfortable, spiritually rich environment. Sometimes, the greatest act of faith is to return to our own communities, to use our experiences and wisdom to uplift those around us, even if it means leaving behind the miraculous manna and the company of giants like Moses. It's about recognizing where we can best serve, where our "candle" can shine brightest.
