Deuteronomy 17:3
2 Suppose a man or woman is discovered among you in one of your villages that the Lord your God is giving you who sins before the Lord your God and breaks his covenant 3 by serving other gods and worshiping them—the sun, moon, or any other heavenly bodies that I have not permitted you to worship. 4 When it is reported to you and you hear about it, you must investigate carefully. If it is indeed true that such a disgraceful thing is being done in Israel,
LXX Deuteronomy 17:3
2 “But if in one of your cities that the Lord your God has given to you there is found a man or woman who will do evil before the Lord your God, to transgress his covenant, 3 and going they serve other gods and worship them, the sun or the moon or any from the host of the heavens that I did not assign, 4 and it is reported to you and you seek it out very much and, look, the thing has taken place, truly this abomination has taken place in Israel;

"... the problem here is that every element he highlights is just as easily accounted for in royal terms. The combined ἔρχοµαι + προσκυνέω (2:2, 8, 11) which is said to “denote a cultic action in the Septuagint” is also used to describe the approach and reverence of royal figures (LXX Genesis 37:10; 42:6; compare Judith 10:23) ... a common way of describing a cultic action by the combined use of ἔρχοµαι + προσκυνέω. While my own investigation did confirm some use of these paired terms in the context of cultic activity such as LXX Deuteronomy 17:3; Jeremiah 33:2 ... Similarly, the combined προσϕέρω + δῶρον (2:11) may often be used in the LXX for cultic offerings to God (particularly throughout Leviticus and Numbers), but it is also often used for tribute paid to royalty (LXX Genesis 43:26; Judges 3:17–18; 3 Kingdoms 2:46), most notably in LXX Psalm 71:10 which, as already noted, is widely accepted as a key background text for Matthew 2 ..."
