Musar zu Jeschijahu 26:8

This is likewise as the prophet said: "to Your Name and to Your remembrance is the lust of [our] soul" (Isaiah 26:8), and "my soul yearns for You in the night; my spirit within me seeks You" (Isaiah 26:9). And David himself said: "when I remember You on my bed, through the night watches I meditate about You" (Tehilim 63:7). Thus he described the pleasure and delight he experienced when speaking of and praising G-d, blessed be His Name. Likewise he said: "I will delight myself in Your Commandments, which I love" (Tehilim 119:47), and "Your testimonies are my delight..." (Tehilim 119:24).
