'Part' in the Bible

Then they came to Zerubbabel and to the heads of families, and said to them, Let us take part in the building with you; for we are servants of your God, even as you are; and we have been making offerings to him from the days of Esar-haddon, king of Assyria, who put us here.

But Zerubbabel, Jeshua, and the other leaders of Israel’s families answered them, “You may have no part with us in building a house for our God, since we alone must build it for Yahweh, the God of Israel, as King Cyrus, the king of Persia has commanded us.”

Now after these things were done, the captains came to me and said, The people of Israel and the priests and Levites have not kept themselves separate from the people of the lands, but have taken part in the disgusting ways of the Canaanites, the Hittites, the Perizzites, the Jebusites, the Ammonites, the Moabites, the Egyptians, and the Amorites.

do we turn back to break Thy commands, and to join ourselves in marriage with the people of these abominations? art not Thou angry against us -- even to consumption -- till there is no remnant and escaped part?
