40 Or “For.” The translation assumes the particle is asseverative (i.e., emphasizing: “certainly”). (Some translations that consider the particle asseverative leave it untranslated.) If taken as causal or explanatory (“for”, cf. ), the verse would explain why the psalmist is pleading for forgiveness, rather than merely offering a sacrifice.
41 The translation assumes that the cohortative is used in a hypothetical manner in a formally unmarked conditional sentence, “You do not want a sacrifice, should I offer [it]” (cf. ). For other examples of cohortatives in the protasis (“if” clause) of a conditional sentence, see §108.e. (It should be noted, however, that understands this particular verse in a different manner. See §108.f, where it is suggested that the cohortative is part of an apodosis with the protasis being suppressed.)
42 You do not desire a burnt sacrifice. The terminology used in v. 16 does not refer to expiatory sacrifices, but to dedication and communion offerings. This is not a categorical denial of the sacrificial system in general or of the importance of such offerings. The psalmist is talking about his specific situation. Dedication and communion offerings have their proper place in worship (see v. 19), but God requires something more fundamental, a repentant and humble attitude (see v. 17), before these offerings can have real meaning.
