'Join' in the Bible

Be it known to the king, that the Jews who have come up from thee unto us, have come in to Jerusalem, the rebellious and base city they are building, and the walls they have finished, and the foundations they join.

The sons of Israel who returned from exile and all those who had separated themselves from the impurity of the nations of the land to join them, to seek the Lord God of Israel, ate the Passover.

Should we again break thy commandments, and join in affinity with the people of these abominations? wouldest not thou be angry with us till thou hadst consumed us, so that there should be no remnant nor escaping?
