Or HaChaim on Exodus 2:10/אור החיים על שמות ב׳:י׳

1"And she called his name, etc. and she said, etc." Here we find a difference from the way Yitzchak and Yaakov and the tribes were named. For all of them, the meaning came before the name itself. For Yitzchak, (Breisheet 21:6), [Sarah said] "anyone who hears will laugh (Yitzchak) etc." and that is when she named him Yitzchak. For Yaakov, (Breisheet 25:26), 'his hand was holding the heel (Ekev) [of Esav] and he called him Yaakov.' With the tribes, [Leah said], 'For Hashem saw ... and she called him Reuven." (Breisheet 29:32), "For Hashem heard ... and she called him Shimon." (Breisheet 29:33) and so on in this manner.
