וַיִּקַּ֥ח יַעֲקֹ֖ב אָ֑בֶן וַיְרִימֶ֖הָ מַצֵּבָֽה׃
Thereupon Jacob took a stone and set it up as a pillar.
Genesis 31:45 (The Contemporary Torah, JPS 2006)
I can't help but notice how many times Jacob takes big rocks and sets them up on end as a way to remember. He did it when he first saw the stairs to heaven. He did it when when he makes a covenant with Laban. Again when he encounters God in Genesis 35. And again in Genesis 35 when Rachel dies.
Nobody else does this. Just Jacob.
