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.
Careless Bible students often make wrongful assumptions for the purpose of God’s interaction with man. One such example involves the reasoning for Israel’s wilderness wanderings. Several alternative explanations might be supposed, but the Bible emphasizes one primary purpose, that of humility. Moses declared this truth to the people when he said, “thou shalt remember all the way which the LORD thy God led thee . . . to humble thee.” He quickly added that God “humbled thee, and suffered thee to hunger, and fed thee with manna.” Deuteronomy 8:16 reemphasizes this truth: “Who fed thee in the wilderness with manna, which thy fathers knew not, that he might humble thee.” The Lord selected Israel’s trials and troublesome path in order to humble them. Truth is frequently that simple but missed by those who read the Bible with preconceived philosophies and concepts.
