2 Chronicles 13:8
And now ye think to withstand the kingdom of the LORD in the hand of the sons of David; and ye be a great multitude, and there are with you golden calves, which Jeroboam made you for gods. And now ye think to withstand the kingdom of the LORD in the hand of the sons of David; and ye be a great multitude, and there are with you golden calves, which Jeroboam made you for gods.
The verse belongs to the account of Jeroboam's reign in Israel and the war between Abijah of Judah and Jeroboam of Israel, in which Judah conquered and Israel was defeated. In that war Judah had four hundred thousand men against Jeroboam's eight hundred thousand, and after Abijah called on the Lord Judah won a decisive victory in which five hundred thousand of Jeroboam's chosen men were slain. It is Abijah's warning that Israel's great multitude and golden calves cannot justify withstanding the kingdom of the Lord in the hand of the sons of David, with the northern kingdom opposing that kingdom and trying to bring it under its power.
The conflict is against the God of Israel and the enduring covenant by which He gave the kingdom to David and his sons, so Israel's opposition ends in defeat. The golden calves that Jeroboam made represented Israel's departure from God and were part of the religious apostasy that began after the kingdom divided. The golden calves are the gods represented in the worship of Dan, and that worship is linked with forsaking God's commandments.
The verse applies to professed worshipers who exalt Sunday as a sign of Baal or sun-worship while claiming that observance is of the Lord and seeking God's word. The conflict between Israel and Judah applies to the American Civil War, in that Jeroboam's revolt and attempt to rule Abijah's kingdom parallel the Southern states' secession and Jefferson Davis's effort to establish his government over the North.
