Consider the following two phrases:

> _noli timere: exaudivit **enim** Deus vocem pueri de loco in quo est_ ([Genesis 21:17b](https://www.biblegateway.com/passage/?search=Genesis+21&version=VULGATE))

>_et benedicentur in semine tuo omnes gentes terrae, **quia** obedisti voci meae_ ([Genesis 22:18](https://www.biblegateway.com/passage/?search=Genesis+22&version=VULGATE))

As I understand them, both are used in the sense of "for/because", but _quia_ normally appears at the beginning of a sentence, whereas _enim_ appears second in the sentence. Is this the only relevant difference, when it comes to the for/because meaning? (They have other meanings too, but my question is not about them.)
