'Bull calves' in the Bible

And he appointed his own priests for the high places and for the goat idols and for the bull calves that he had made.

So now you yourselves are considering [that you are] strong before the kingdom of Yahweh [which is] in the hand the sons of David, since you yourselves are a great multitude and you have bull calves of gold that Jeroboam has made for idols.

And now they sin again, and they make for themselves a molten idol, idols from their silver metal according to their understanding, all of them the work of skilled craftsmen. To these they say, "Sacrifice!" People are kissing bull calves.

[Alas for] those who lie on beds of ivory and lounge on their couches, and those eating young rams from [the] sheep and goats, and bull-calves from the middle of [the] animal stall.

With what shall I approach Yahweh, and bow down to God on high? Shall I approach him with burnt offerings, with bull calves a year old?
