Мидраш к Берешит 13:4

And the children of Israel lifted up their eyes … and they were sore afraid (Exod. 14:10). They resorted to the practices of their fathers. It is written of Abraham: And he called upon the name of the Lord (Gen. 12:8), of Isaac it is stated And Isaac went out to meditate in the field (ibid. 24:63), and of Jacob it is stated: And he lighted upon the place (ibid. 28:11). The expression lighted upon (vayifga) is employed with reference to prayer, as it is said: Therefore pray not thou for this people, neither lift up cry nor prayer for them; neither make intercession (tifga) to Me (Jer. 7:16).
