¹ tc Heb “their inward part [is] their houses [are] permanent, their dwelling places for a generation and a generation.” If one follows the MT, then קֶרֶב (qerev, “inward part”) must refer to the seat of these people’s thoughts (for other examples of this use of the term, see BDB 899 s.v., though BDB prefers an emendation in this passage). In this case all three lines of v. 11 expose these people’s arrogant assumption that they will last forever, which then stands in sharp contrast to reality as summarized in v. 12. In this case one might translate the first two lines, “they think that their houses are permanent and that their dwelling places will last forever” (cf. NASB). Following the lead of several ancient versions, the present translation assumes an emendation of קִרְבָּם (qirbam, “their inward part”) to קְבָרִים (qÿvarim, “graves”). This assumes that the letters bet (ב) and resh (ר) were accidentally transposed in the MT. In this case the first two lines support the point made in v. 10, while the third line of v. 11 stands in contrast to v. 12. The phrase בֵּית עוֹלָם (bet ’olam, “permanent house”) is used of a tomb in Eccl 12:5 (as well as in Phoenician tomb inscriptions, see DNWSI 1:160 for a list of texts) and מִשְׁכָּן (mishkan, “dwelling place”) refers to a tomb in Isa 22:16. Cf. NEB, NIV, NRSV.
