1 tn Heb “sacrifice and offering you do not desire.” The statement is exaggerated for the sake of emphasis (see Ps 51:16 as well). God is pleased with sacrifices, but his first priority is obedience and loyalty (see 1 Sam 15:22). Sacrifices and offerings apart from genuine allegiance are meaningless (see Isa 1:11-20).
2 tn Heb “ears you hollowed out for me.” The meaning of this odd expression is debated (this is the only collocation of “hollowed out” and “ears” in the OT). It may have been an idiomatic expression referring to making a point clear to a listener. The LXX has “but a body you have prepared for me,” a reading which is followed in Heb 10:5.
3 tn Heb “in the roll of the scroll it is written concerning me.” Apparently the psalmist refers to the law of God (see v. 8), which contains the commandments God desires him to obey. If this is a distinctly royal psalm, then the psalmist/king may be referring specifically to the regulations of kingship prescribed in Deut 17:14-20. See P. C. Craigie, Psalms 1-50 (WBC), 315.
