'Altars' in the Bible

Because Ephraim did multiply altars to sin, They have been to him altars to sin.

An empty vine is Israel, Fruit he maketh like to himself, According to the abundance of his fruit, He hath multiplied for the altars, According to the goodness of his land, They have made goodly standing-pillars.

Their heart hath been divided, now they are guilty, He doth break down their altars, He doth destroy their standing-pillars.

And destroyed have been high places of Aven, the sin of Israel. Thorn and bramble go up on their altars, And they have said to hills, Cover us, And to heights, Fall upon us.

Surely Gilead is iniquity, Only, vanity they have been, In Gilead bullocks they have sacrificed, Also their altars are as heaps, on the furrows of a field.
