시편 92:4의 미드라쉬

"Upon a ten-stringed instrument and upon the psaltery" (Ps. 92:8). All testimonies reliable to Israel are (celebrated) with ten (males). The harp upon which David played had ten strings. The testimony for the dead is through ten (males). The testimony for the (public) benediction of (God's) Name is through ten (males). The testimony of the covenant of circumcision is through ten (males). The testimony for Chalizah is through ten (males), as it is said, "And he took ten men of the elders of the city" (Ruth 4:2).

The Holy One, blessed be He, said: I desire of Israel the meditation of their mouths like the psaltery and an instrument of ten strings, as it is said, "With the meditation of || the harp" (Ps. 92:3).

"For thou, O Lord, hast made me glad through thy work" (Ps. 92:4). Adam said: The Holy One, blessed be He, had made me glad and brought me into the garden of Eden, and showed me the place of the abode of the righteous in the garden of Eden, and He showed me the four kingdoms, their rule and their destruction; and He showed me David, the son of Jesse, and his dominion in the future that is to come. I took from my years seventy years and added them to his days, as it is said, "Thou wilt add days to the days of the king; his years shall be as many generations" (Ps. 61:6). The Holy One, blessed be He, said to him: Thou wilt add days to the days of (the king Messiah); I also will add to his years in the future which is to come, as though they were many generations, as it is said, "His years shall be as many generations" (ibid.). I have given to God praise, and song (lauding) His works, as it is said, "I will sing of the works of thy hands" (Ps. 92:4).
