Study 51 From the Book of Psalms is: Psalms 66 and 67
Ps. 66 is a summons to the nations to join in praise to God for a great deliverance which He has wrought for His people, such as the deliverance of Jerusalem from Sennacherib. If this was the occasion, the speaker in verses 13:20 may well be King Hezekiah himself, speaking as the representative of the nation. Ps. 67 may belong to the same time. See Is. 37
Ps. 66. Note in detail what God is here said to do with an for His people. What response ought this to move me to make? What is the condition of sharing in such an experience?
Ps. 67. Do we share the longing of the psalmist that all nations might knows God and His salvation? By what means did he think it would be achieved? Cf. Mt.5:14-16; 1 Pet. 2:9, 10.
