Commutative Algebra, chapter X, § 1. Profondeur

One has sup⁡p∈Ass⁡(M)dim⁡(A/p)=dim⁡(M)\sup_{p \in \operatorname{Ass}(M)} \dim(A/p) = \dim(M) (VIII, § 1, No. 4, remark 2), and one recovers the inequality prof(M)≤dim⁡(M)prof(M) \leq \dim(M) for M≠0M \neq 0 (No. 4, cor. 2 of th. 2).

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
