ק֚וּם הִתְהַלֵּ֣ךְ בָּאָ֔רֶץ לְאָרְכָּ֖הּ וּלְרָחְבָּ֑הּ כִּ֥י לְךָ֖ אֶתְּנֶֽנָּה׃
Levántate, ve por la tierra á lo largo de ella y á su ancho; porque á ti la tengo de dar.
Jerusalem Talmud Kiddushin
This does not follow Rebbi Eliezer, for Rebbi Eliezer said that walking acquires. If one walked across a field in length and breadth, he acquired up to the place he walked, the words of Rebbi Eliezer. But the Sages say that he did not acquire up to the moment he acted in possession. Everybody agrees that if somebody sells a path to another, when the latter went, he acquired. What is the reason? “Arise, walk in the Land, etc.”
