Psalms 71:17

thou hast taught me&c. He has been a life-long disciple in the school of God. Cp. Isaiah 8:16; Isaiah 50:4; Isaiah 54:13.

have I declared Have I been declaring, habitually and constantly.

thy wondrous works A special term for the singular and conspicuous works of God, both in nature (Job 5:9), and in His dealings with His people (Exodus 3:20), particularly in the great crises of their history (Psalms 78:4; Psalms 78:11; Psalms 78:32), which declare His power and love, and arouse the admiration of all who behold them. The word includes -miracles" commonly so called, as one limited class of -the wonderful works of God," but is of much wider application. To recount and celebrate His marvellous works is the duty and delight of God's saints. Cp. Psalms 9:1; Psalms 26:7; Psalms 40:5.
