'Built an Altar' in the Bible

Then Joshua built an altar unto the LORD God of Israel in mount Ebal,

When they came to the region of the Jordan which is in the land of Canaan, the sons of Reuben and the sons of Gad and the half-tribe of Manasseh built an altar there by the Jordan, a large altar in appearance.

And the children of Israel heard say, Behold, the children of Reuben and the children of Gad and the half tribe of Manasseh have built an altar over against the land of Canaan, in the borders of Jordan, at the passage of the children of Israel.

"The entire community of the Lord says, 'Why have you disobeyed the God of Israel by turning back today from following the Lord? You built an altar for yourselves and have rebelled today against the Lord.

If we have built an altar for ourselves intended to turn us away from following the LORD, or to offer burnt offerings, grain offerings, or peace offerings on it, may the LORD himself demand an accounting from us!
