Commentary for Leviticus 2:7

מרחשת [AND IF THOU BRING A MEAL OFFERING PREPARED IN A] מרחשת — This was a vessel used in the Temple, a deep one, and because it was deep the oil in it was heaped up (of considerable depth) and the fire did not burn it, and therefore the meal-offering made in it was, as it were, creeping). Every thing that is soft (elastic) because of the liquid contained in it appears as though it were creeping and moving (Sifra, Vayikra Dibbura d'Nedavah, Chapter 12 7; Menachot 63a).
