Eretz Yisrael Is Acquired With Suffering

"נחלתכם חבל כנען ארץ את אתן לך לאמר"

Harav Raphael Emmanuel Chai Riki explained: Chazal say (Brachos 5a) that Eretz Yisrael is acquired with yissurim, and that is why it is called in this passuk "chevel nachalaschem" – because the "chevel" is a term for yissurim, such as "chevlei leidah," birth pangs.
