Ive noticed pretty much all christian names that have j in it (joseph, jacob, etc.) have h instead in armenian (hovsepian, hacob)

Now i dont know a lot about armenian but i skimmed some wiki pages and a bit of a paper on the phonologial development of armenian but i could find no such j to h shift and also it seems like a pretty strange soundchange that i dont recall ever seeing in another language, so why is this the case? And do other borrowings that arent names also display this shit?
