(Amos 3:2) The nation of Israel was used to make living pictures or types, foreshadowing better things to come; and those who study the Scriptural account of Israel's experiences are able to approximate closely future events which will be good for mankind .-- 1 Corinthians 10:1-13; Hebrews 10:1.
[3]With the nation of Israel the harp was an instrument consecrated to joy and exaltation.

David, who for forty years was king of Israel, was an expert player on the harp, and it will be noted that in the Psalms often the harp is used to symbolize or teach some great truth.

The Jews used this instrument on occasions of joy, such as jubilees and festivals.
[4]Josephus, a writer of Jewish history, is authority for the statement that the harp usually had ten strings, but that at times it was smaller and had only eight strings.

The number _ten_ is used in the Scriptures to symbolize that which is complete or perfect as pertaining to man.

We would understand, then, that the harp with ten strings pictures the great fundamental truths concerning the divine plan.
