this is my name for ever
The name here referred to is that which immediately precedes, [yhwh,] ,] {Yehowah,} which we translate "Lord", the name by which God had been known from the creation of the world, (Ge 2:2,) and by which he is known to the present day. [yhwh,] {Yehowah,} from [hwh,] {hawah,} to be, subsist, signifies "He who is", or "subsists", i.e., eminently and in a manner superior to all other beings; and is essentially the same with [ahwh,] {eheyeh,} "I AM", in the preceding verse.
