“Hearing” in the Bible means more than just the collection of atmospheric vibrations: It represents receiving and understanding new ideas, particularly those from the Lord. On a deeper level it represents obedience, because we must understand to obey. This also is reflected in natural language, in which we often use “hear” to mean “obey.” There are many shades of meaning beyond that, depending on context -- who is hearing whom, and what the subject at hand is.

356. Internal Meaning of Psalm 106

Of the church instituted among the Jewish nation: it became perverted and revolted. (3)

1-5 Prayer of the Lord to the Father to give help, that He might see the church established. (13, 11, 3)

6-8 Although those who were of the church beheld Divine miracles, they backslid, and yet they were preserved, (3)

9-34 as at the sea Suph and afterwards in the desert (many [instances here recounted]), nevertheless they rebelled. (3)

35-39 They totally destroyed and profaned the truths and goods of the church. (3)

40-43 Therefore the church with them was forsaken by the Lord, and destroyed. (3)

44-46 Then those who were out of the church were heard, (11)

47-48 and a church constituted of them will arise and will worship the Lord. (11, 8)
