Job 15:8 New English Translation

⁸Do you listen in on God’s secret council?^[a]
Do you limit^[b] wisdom to yourself?

Job 15:8 tn The meaning of סוֹד (sod) is “confidence.” In the context the implication is “secret counsel” of the Lord God (see Jer 23:18). It is a question of confidence on the part of God, that only wisdom can know (see Prov 8:30, 31). Job seemed to them to claim to have access to the mind of God.
Job 15:8 tn In v. 4 the word meant “limit”; here it has a slightly different sense, namely, “to reserve for oneself.”
