One who reads the Shema and makes a mistake, and [he] does not know where he made the mistake, [he] should go back to the beginning of the [first] paragraph. If he made a mistake in the middle of a paragraph, he should go back to the beginning of [that] paragraph. If he made a mistake between the first [verse that mentions] writing and the second [verse that mentions] writing, he should go back to the first [verse that mentions] writing.

Workers [must] read [the Shema even while they are sitting] on top of a tree. And they [can] pray [Shmoneh Esreh] on top of an olive tree or on top of a fig tree. But [if they are on top of] all other trees, they [must] go down to pray [Shmoneh Esreh]. The owner of the house [must] go down regardless [what kind of tree he is on top of] and pray [Shmoneh Esreh]. Workers [must] read the Shema and say a Beracha (blessing) before it and after it. [When] they eat their bread they [must] say the Beracha before it and after it. And they [must] pray three times [a day] Shmoneh Esreh, but they do not go in front of the pulpit [to lead the congregation].
