כאיש אחד, בלב אחד: Let’s Unify In Support of Each Other and the Whole World

(1) On the third new moon after the Israelites had gone forth from the land of Egypt, on that very day, they entered the wilderness of Sinai. (2) Having journeyed from Rephidim, they entered the wilderness of Sinai and encamped in the wilderness. Israel encamped there in front of the mountain.

(10) (Exodus 19:2) "And Israel encamped there": Elsewhere it is written "and they journeyed," "and they encamped" — they journeyed in quarrel and encamped in quarrel. Here, they were of one heart — wherefore it is written "and (it) encamped."

(the third thing is) the teaching of the wise coming together with each other, and connecting with a full and whole friendship (heart). Not to be separated from each other, as for that the Talmud teaches us based on the words of Jeremiah, that it's like a sword on those who are [studying] alone. But, we need to come together, grow from each other [from the differences], and treat each other nicely. That is why the Torah uses a singular word, because all the Israelites became like one person - and now they were ready to receive to Torah.

And they all came together in a covenant, ”We will do and we will listen,” they said as one. And they opened and answered, “God is one,” Blessed is the One who gives strength to the the tired. (translation by Abby Stein)
