15. Proclaim his glory in grateful praise! To the music of the harp, sing this song:
16. All that the Lord has done is very good;all that he commands is sooner or later done.
17. No one should ask why things are as they are;these questions will be answered at the right time.He commanded, and the water piled up high,great walls of water arose when he spoke.
18. Whatever he commands is promptly done;there are no limits to his power to save.
