Deuteronomy 30:11-14 -

The fulfillment of this condition was not impossible or even difficult; for God had done everything to render it easy for them. The commandment of God was not hidden from them ; literally, was not wonderful to them ; i . e . hard to be understood or to perform (see the use of the Hebrew word in Psalms 131:1 ; Proverbs 30:18 ); nor was it far off; it was not in heaven — i . e . though heavenly in its source, it had not remained there, but had been revealed—so that there was no need for any one to say, Who will ascend to heaven, and bring it down to us, that we may hear it, and do it? The idea is not, as Keil suggests, that of "an inaccessible height" which none could scale; nor is it, as suggested by Knobel, that of something "incomprehensible, impracticable, and superhuman;" it is simply a statement of fact that the Law had not been retained in heaven, but had been revealed to men. Nor was this revelation made in some far distant place across the sea, so that any need say, Who will go over the sea for us, and bring it unto us, that we may hear it, and do it? On the contrary, it was very near to them, had been disclosed in words so that they could utter it with their own mouth, converse over it, and ponder it in their hearts (cf. Isaiah 45:19 ; Jeremiah 23:28 ; Romans 10:6 ). In the allusion to the sea, the representation is not that of depth (Targum Jon.), but that of distance.
