*73 Mr. Justice Sutherland

delivered the opinion of the Court.

The respondent Ross is a trustee in bankruptcy. The estate of the bankrupt was indebted to the State of Missouri for taxes in the sum of $8,366.38, with interest, and to the City of St. Louis for taxes in the sum of $8,972.30 and interest. The funds of the estate were insufficient to pay these taxes in full. The referee held that the claims of the state and city were of equal rank under § 64 of the Bankruptcy Act, and that the available funds should be prorated between the claims according to their respective amounts. He therefore denied the motion of the state for priority.

The order of the referee was approved and confirmed by the district court; and upon appeal to the circuit court of appeals, the order of the district court was affirmed. 80 F. (2d) 329.

The referee and both courts proceeded upon the theory that by § 64 b, ¶ 6, of the Bankruptcy Act, all taxes, whether of the United States, state, county, district or municipality, were placed on a parity. We agree with that view.

Section 64a requires the payment of all taxes “legally due and owing by the bankrupt to the United States, State, county, district, or municipality, in the order of priority as set forth' in paragraph (b) hereof.” Paragraph (b) prescribes the order of priority in which debts shall be paid in advance of the payment of dividends to creditors, the sixth order being “taxes payable under paragraph (a) hereof,” and .the seventh order being “debts owing to any person who by the laws of the States or the United States is entitled to priority.” The text of paragraph (b) in full appears in the margin. 1

*74 First. By this enumeration it is clear that Congress intended to establish seven distinct classes of indebtedness and establish their priority in respect of one another in the order set forth. When it came to the sixth paragraph, it embodied taxes payable under paragraph (a), there enumerated as taxes due the United States, state, county, district, or municipality. The intention clearly was to put these various governmental units in respect of their taxes in a single class upon terms of equality with one another. Since Congress was at pains to set forth the order of priority in distinct paragraphs under separate numerals, we *75 are unable to reach any other conclusion. If it had been intended to establish priorities as among the governmental units named in the order in which they appear in the 6th paragraph, the very structure of § 64 b plainly suggests that each would have appeared under a separate numeral instead of all being grouped under a single numeral.

In New Jersey v. Anderson, 203 U. S. 483, 489, this court specifically said1: “The requirement of the present law is a wide departure from the Act of 1867, and specifically obliges the trustee to pay all taxes legally due and owing, without distinction between the United States and the State, county, district, or municipality.” It is true that this statement was not necessary to the decision; but it nevertheless correctly states our view as to the meaning of the clause under consideration, and is now definitely approved. The decision in that case was made nearly thirty years ago, since which time the lower federal courts have almost unanimously followed the rule there stated. We deem it unnecessary to review the decisions, since that has been carefully done by the referee in his certificate, and by the court in its opinion. Among the cases are the following: In re A. E. Fountain, Inc., 295 Fed. 873, 874; In re Wyley Co., 292 Fed. 900, 902; In re A. J. Waterman Mfg. Co., 291 Fed. 589, 594. These decisions are plainly correct; but if they were doubtful, we should at this late day hesitate to disturb them. United States v. Ryan, 284 U. S. 167, 174. Moreover, Congress in the face of these decisions has permitted the clause as it now appears in paragraph (6) to stand for many years without change in its phraseology, although amending that portion of the Bankruptcy Act in other particulars. This is persuasive evidence of the adoption by that body of the judicial construction. United States v. Ryan, supra, at p. 175; Sessions v. Romadka, 145 U. S. 29, 41-42.

*76 . Second. The state urges that the question is controlled .by paragraph (7), which gives priority in the seventh degree to “debts owing to any person who by the laws of the States ... is entitled to priority.” Section 3152, Rev. Stat. Missouri, 1929, provides that in cases of insolvency, debts due the state shall be first satisfied, and that this priority shall extend to cases in which an act of bankruptcy is committed. The contention is that unpaid taxes constitute debts, and therefore fall within the seventh paragraph. But this conclusion must be rejected; for conceding that taxes are debts, they are carved out of the general provisions of paragraph (7) and put in a special class under paragraph (6), and thus fall within the rule that special provisions prevail over general ones which, in the absence of the special provisions, would control. Townsend v. Little, 109 U. S. 504, 512; McKee v. United States, 164 U. S. 287, 294; Kepner v. United States, 195 U. S. 100, 125; In re Rouse, Hazard & Co., 91 Fed. 96, 101; In re Slomka, 122 Fed. 630, 631.

Decree affirmed.
