The Talmud in tractate Sotah 46b emphasizes the reward for escorting Jews that are in danger.
The following is primarily the translation of Soncino of that text at
http://halakhah.com/pdf/nashim/Sotah.pdfThey then declare, ‘Our hands have not shed this blood, neither have our eyes
seen it’{Dvarim/Deut.21:7}. But can it enter our minds that [the members of a] Court of Justice shed blood! [The
meaning of their statement is], however, [The man found dead] did not come to us for help and we
dismissed him without supplying him with food, we did not see him and let him go without an
escort.It has been taught: R. Meir used to say: We may compel a person to escort [a traveller],
{Soncino: Or the court compels a town to provide escorts for travelers}
because the reward for escorting is limitless; as it is said: And the watchers saw a man come forth
out of the city, and they said unto him, Shew us, we pray thee, the entrance into the city, and we will
deal kindly with thee.{Shoftim/Judges 1:24} It continues, And he shewed them the entrance into the city.{ibid, verse 25} What was the
kindness they did to him? They slew the whole of the city at the edge of the sword, but let that man
and his family go.
And the man went into the land of the Hittites, and built a city, and called the name thereof Luz:
which is the name thereof unto this day{ibid, verse26}.
It has been taught: That is the Luz in which they dye the
Blue/Tekhelet {Soncino:For the fringes (Num. XV, 38). The purpose of this statement and what follows is to illustrate the words ‘which is the name thereof unto this day’, showing that the city survived destruction and still exists.}; that is the Luz against which Sennacherib marched without disturbing it, against which
Nebuchadnezzar marched without destroying it, and even the Angel of Death has no permission to
pass through it, but when the old men there become tired of life they go outside the wall and then
die.
For is not the matter an a fortiori inference{Kal Vachomer}? If this Canaanite, who did not utter a word or walk
a step, caused deliverance to come to himself and his seed unto the end of all generations, how
much more so he who performs the act of escorting by actually going with the person!
How did he show them [the way]? — Hezekiah said: He just curved his mouth for them; R. Johanan said: He
pointed for them with his finger. There is a teaching in agreement with R. Johanan, viz., Because this
Canaanite pointed with his finger, he caused deliverance to come to himself and his seed unto the
end of all generations.
