Beibl.net is a cracking translation of the Bible into Welsh; the language is simple enough that I understand it with very little trouble, and knowing the English verses allows you to fill in the words you don’t know through guesswork. If you’re looking for something to help expand your vocabulary, I can’t recommend it enough
Considering the translation was finished in '15, the language is also far more modern and colloquial/slangy than in the older William Morgan Bible/Beibl Newydd Cymru, so no need to worry about understanding your _yr ydwyf yn_s!
(Note, I’m not really trying to start a religious discussion, since those rarely end well, just wanted to share what I’ve been finding a nice resource to help expand my vocabulary/serve as understanding practice )
