אַל־תַּאֲמִ֣ינוּ בְרֵ֔עַ אַֽל־תִּבְטְח֖וּ בְּאַלּ֑וּף מִשֹּׁכֶ֣בֶת חֵיקֶ֔ךָ שְׁמֹ֖ר פִּתְחֵי־פִֽיךָ׃
Huwag kayong magtiwala sa kaibigan, huwag kayong umasa sa matalik na kasama; maging sa babaing nakahiga sa iyong kandungan ay bantayan mo ang mga pintuan ng iyong bibig.
Chagigah
Rabbi Yehudah the son of Rabbi Nachmani, the translator of Reish Lakish, expounded: "What is [the meaning] of the verse, 'Do not trust in a friend, do not put confidence in a familiar friend (Micah 7:5)'? If the evil inclination tells you, 'Sin, and the Holy One, Blessed be He, will forgive,' do not trust [him, as it is said], 'do not trust in a friend (heb. Rei'a)'. And there is no [term] 'friend' except for the evil inclination, as it is said, 'For the inclination of the heart of the man is evil (heb. Ra, with same letters as Rei'a) (Genesis 8:21).'

And the sages say, "The soul of a person testifies against him, as it is said, 'From that which sleeps in your bosom, guard your mouth (Micah 7:5).' What is the thing that sleeps in the bosom of a man? You should say, this is the soul." R' Zerikah said, "The two accompanying angels, which escort him, they testify against him, as it is said, 'For he shall command his angels to guard you through all your ways (Psalms 91:11).'" [And the sages say,] The limbs of a man testify against him, as it is said, 'And you are My witnesses, Hashem declares, And I am G-d (Isaiah 43:12).'"
