12 For the priesthood being changed, of necessity there is also a change of the law. 13 For He of whom these things are spoken belongs to another tribe, from which no man has officiated at the altar. 14 For it is evident that our Lord arose from Judah, of which tribe Moses spoke nothing concerning priesthood. (Hebrews 7:12–14, NKJV)
Properly handling God’s word includes respecting the silence of the Scriptures (2 Tim. 2:15). At times God says, “thou shalt not,” but that is not the only way He reveals His will. The double negative, “It doesn’t say not to,” fails to prove God’s approval. Yet, many use it to justify moral and religious decisions. We must search for what God says on a matter, content that it is sufficient for us to know and to follow (cf. Deut. 29:29). The Hebrew writer used the silence of the Scriptures in today’s passage. He arrived at the unavoidable conclusion (a necessary inference) that the law had to change because the priesthood had changed (v. 11; Heb. 6:20). He explained that only Levites could be priests under the Law of Moses (Num. 3:10). Yet, Moses never directly said, “You shall not have priests from the tribes of Judah, Ephraim, Benjamin, etc.” He did not need to. Moses said what God wanted, priests from Levi. All other tribes were necessarily excluded. Even though Moses did not leave a “thou shalt not” list, Israel knew the correct application. There was no authority for priests from other tribes. Thus, the law itself had to be changed for Christ to be High Priest. God’s silence restrains, it does not free us to act. Let us find what God says, for that is what He approves. Then, “hold fast what is good” (1 Thess. 5:21).
