Thus the Hebrew ruach is rendered by nous in 1 Corinthians 2:16 ('mind of the Lord,' with reference to Isaiah 40:13, where 'ruach YHWH (spirit of Yahweh)' occurs). Here too several terms are rendered by the same word.

In the New Testament the words nous and dianoia are used, but not with any precision of meaning. Thus we read in The Wisdom of Solomon 9:15, 'For the corruptible body (soma) presseth down the soul (psuche) and the earthly tabernacle weigheth down the mind (nous) that museth upon many things.' But these distinctions are alien to the letter and spirit of revelation, a product of the Greek and not of the Hebrew mind. In the Apocrypha this precision is equally lacking. Sometimes lebh is used, as in Isaiah 46:8, 'bring it to mind' (literally, 'heart'), or in Psalms 31:12, 'I am forgotten as a dead man out of mind' (literally, 'heart'), as in Septuagint, kardia, and in Vulgate, a corde, Luther, im Herzen, new Dutch translated, uit de gedachtenis (i.e. Here Luther renders the term Herzeleid ('grief of heart'), and the Vulgate (Jerome's Latin Bible, 390-405 A.D.) animum. Sometimes nephesh or 'soul' is rendered by 'mind' ( Deuteronomy 18:6 the King James Version, 'desire of his soul' or 'mind') sometimes ruah or 'spirit' ( Genesis 26:35, 'grief of mind,' ruah). We are often misled by the different renderings in the different versions, both early and late. In the Old Testament lebh is made to stand for the various manifestations of our intellectual and emotional nature. We look in vain in the Old Testament and New Testament for anything like scientific precision in the employment of terms which are meant to indicate mental operations.
