Psalm 119 is filled with statements promoting the necessity of the word of God. Seven times in this psalm we find a statement declaring the writer’s desire to meditate upon the words of God. Three of these times he states emphatically that he will meditate in God’s statutes or His precepts (Psalm 119:15, 48, 78). Not only was meditating upon God’s words something that the psalmist desired to do in the future, but he had formed this habit long ago (Psalm 119:23, 99). The writer of this psalm, like other successful believers in the past, made it common practice to meditate in the words of God both day and night (Psalm 119:97; Psalm 1:2; Joshua 1:8).
Reading commentaries offers varying opinions concerning the definition of purity. However, the Bible offers some exacting details which give the right definition. Today's passage speaks of the “pure blood of the grape.” In other words, nothing was added to the juice—it was pure. There are several other substances in scripture identified as pure: gold (Exodus 25:39), olive oil (Exodus 27:20), myrrh (Exodus 30:23), incense (Exodus 37:29), and language (Zephaniah 3:9). Each instance emphasizes that nothing exists to corrupt the nature of the original. These substances are not combined with other materials to dilute or defile them. In essence, purity demands the absence of any substance that corrupts, defiles, or taints in any way.
