Midrash Tanchuma
And Jacob went out from Beer-sheba (Gen. 28:10). May it please our master to teach us where a man who has unintentionally taken the life of another man may take refuge. Thus do our masters teach us: A man who has unintentionally killed another person may take refuge either in one of the three cities of refuge in Trans-Jordan or in one of the three cities in Canaan.1The three cities of refuge on the other side of the Jordan were Bezer in the territory of Reuben, Ramouth in the territory of Gad, and Golan in the territory of Manasseh; the cities in Canaan were Kadesh in the territory of Naphtali, Shechem in Ephraim, and Hebron in Judah. Our patriarch Jacob took refuge in Haran. He fled there because he feared that his wicked brother, Esau, would slay him. When the Holy One, blessed be He, saw that Jacob was deeply distressed, He appeared before him in a dream. R. Abahu said in the name of R. Simeon the son of Lakish: As soon as the stones beneath his head beheld the glory of the Holy One, blessed be He, they dissolved into each other and formed one stone. Whence do we know this? Before he went to sleep, Scripture states: He took stones of the place (Gen. 28:11), but after he awakened, it is written: He took the stone (ibid., v. 18).

“The Lord spoke to Moses and to Aaron, saying” (Numbers 2:1).
“The Lord spoke to Moses and to Aaron, saying.” In eighteen places you find Moses and Aaron as equals, corresponding to the eighteen blessings. The three patriarchs, from there you find a fixed obligation that one prays three times daily. Abraham instituted the morning prayer, as it is stated: “Abraham arose early in the morning [to the place where he had stood before the Lord]” (Genesis 19:27). Standing is nothing other than prayer, as it is stated: “Pinḥas stood and prayed” (Psalms 106:30). Isaac instituted the afternoon prayer, as it is stated: “Isaac went out to stroll [lasuaḥ]” (Genesis 24:63). Siḥa is nothing other than prayer, as it is stated: “The prayer of a poor man when he is faint [and pours out his plea [siḥo] before the Lord]” (Psalms 102:1). Jacob instituted the evening prayer, as it is stated: “He encountered [vayifga] the place…” (Genesis 28:11). Pegia is nothing other than prayer, as it is stated: “And you, do not pray on behalf of this people…[and do not plead [tifga] with Me]” (Jeremiah 7:16). In eighteen places Moses and Aaron are paired.
An allusion to the eighteen blessings; they correspond to the eighteen mentions of God’s name that are written in Shema Yisrael and in: “A psalm by David. Give to the Lord, sons of the mighty” (Psalms 29:1). The three patriarchs instituted that one prays three times daily, and Moses and Aaron [are paired in eighteen places], and from these eighteen mentions of God’s name we derived eighteen blessings.

Midrash Tanchuma Buber
Another interpretation (of Gen. 28:10): AND JACOB SET OUT. This text is related (to Prov. 6:22): WHEN YOU WALK, IT (your father's commandment and your mother's torah) WILL GUIDE YOU. This refers to Jacob, who had been occupied with Torah when he set out from his father's house, and he did not leave it behind. Thus it is stated (ibid., cont.): IN YOUR LYING DOWN, IT WILL WATCH OVER YOU. When? (In Gen. 28:11:) THEN HE TOOK ONE OF THE STONES OF THE PLACE, [SET IT UNDER HIS HEAD, AND LAY DOWN IN THAT PLACE]. When he lay down, it guarded him. (Prov. 6:22, cont.:) AND WHEN YOU AWAKEN, IT WILL CONVERSE WITH YOU. [(Gen. 28:16:) THEN JACOB AWAKENED FROM HIS SLEEP.]
