'Cultic' in the Bible

And in accord with the ordinance of David his father he appointed working groups of priests for their service, Levites for their responsibilities for praise and cultic service before the priests {according to the daily requirement}, and the gatekeepers in their working groups, gate by gate. For thus David the man of God had commanded.

In addition to all of this, he built high places in the mountains of Judah, led the inhabitants of Jerusalem into cultic sexual immorality, and made Judah go astray.

"This is what the LORD God of your ancestor David says: "You haven't lived like your father Jehoshaphat and like King Asa of Judah. Instead, you have lived like the kings of Israel by causing Judah and the inhabitants of Jerusalem to commit cultic sexual immorality just like Ahab's dynasty did! And you've killed your brothers who were better than you your own father's dynasty!
