“See, I have set before thee this day life and good, and death and evil;”
King James Version (KJV)
30:13 Neither beyond the sea - The knowledge of this commandment is not to be fetched from far distant places, to which divers of the wise Heathens travelled for their wisdom; but it was brought to thy very doors and ears, and declared to thee in this wilderness.
30:14 In thy mouth - Thou knowest it so well, that it is the matter of thy common discourse. In thy heart - In thy mind, (as the heart is very commonly taken) to understand and believe it. In a word, the Law is plain and easy: but the gospel is much more so.
