Yesaya 40:13

40:13 Who comprehends ¹  the mind ²  of the Lord,

or gives him instruction as his counselor? ³ 

Roma 11:34

11:34 For who has known the mind of the Lord,

or who has been his counselor? ⁴ 

[40:13]  ¹ tn Perhaps the verb is used metonymically here in the sense of “advises” (note the following line).

[40:13]  ² tn In this context רוּחַ (ruakh) likely refers to the Lord’s “mind,” or mental faculties, rather than his personal Spirit (see BDB 925 s.v.).

[40:13]  ³ tn Heb “or [as] the man of his counsel causes him to know?”

[11:34]  ⁴ sn A quotation from Isa 40:13.
