From what i was told, we don't celebrate birthdays because the only two times it is mentioned in the bible, bad things happened. So if the WT wants to set standards by the "two bad things" rule, then why do they use the name Bethel? I've read two instances in the bible where bad things happened there. The one in 1 kings
28c The king took counsel, made two calves of gold, and said to the people: “You have been going up to Jerusalem long enough. Here are your gods, O Israel, who brought you up from the land of Egypt.” 29d And he put one in Bethel, the other in Dan.*
2 kings 2
23 And he went up from thence unto Bethel: and as he was going up by the way, there came forth little children out of the city, and mocked him, and said unto him, Go up, thou bald head; go up, thou bald head.
24 And he turned back, and looked on them, and cursed them in the name of the LORD. And there came forth two she bears out of the wood, and tare forty and two children of them.
