As the people journeyed through the wilderness, many precious lessons were fixed in their minds by means of song. At their deliverance from Pharaoh's army the whole host of Israel had joined in the song of triumph. Far over desert and sea rang the joyous refrain, and the mountains re-echoed the accents of praise, "Sing ye to the Lord, for He hath triumphed gloriously." Exodus 15:21. Often on the journey was this song repeated, cheering the hearts and kindling the faith of the pilgrim travelers. The commandments as given from Sinai, with promises of God's favor and records of His wonderful works for their deliverance, were by divine direction expressed in song, and were chanted to the sound of instrumental music, the people keeping step as their voices united in praise.

Mens folket drog gennem ørkenen, blev mange værdifulde lærdomme indprentet dem ved hjælp af sang. Ved udfrielsen fra Faraos hær forenede hele Israels skare sig i en sejrssang. Vidt over ørken og hav klang det jublende omkvæd, og bjergene gav genlyd af lovsangstonerne:»Syng for Herren, thi han er højt ophøjet.« 2Mos. 15,21. Denne sang blev ofte gentaget under vandringen, hvor den opmuntrede hjerterne og gjorde troen mere brændende hos pilgrimmene. De bud, der var blevet givet dem på Sinaj, med løfter om Guds velbehag og beretningerne om hans underfulde gerninger for at udfri dem, fik efter guddommelig anvisning udtryk i sang og blev sunget med ledsagelse af musikinstrumenternes klang, mens folket holdt trit, idet deres stemmer forenede sig i lovsangen.
