What Does the Bible Say About Holiness?

"Then Moses and the children of Israel sang this song to the LORD, and said, “I will sing to the LORD, for he has triumphed gloriously. He has thrown the horse and his rider into the sea. The LORD is my strength and song. He has become my salvation. This is my God, and I will praise him; my father’s God, and I will exalt him. The LORD is a man of war. The LORD is his name. He has cast Pharaoh’s chariots and his army into the sea. His chosen captains are sunk in the Red Sea. The deeps cover them. They went down into the depths like a stone. Your right hand, LORD, is glorious in power. Your right hand, LORD, dashes the enemy in pieces. In the greatness of your excellency, you overthrow those who rise up against you. You send out your wrath. It consumes them as stubble. With the blast of your nostrils, the waters were piled up. The floods stood upright as a heap. The deeps were congealed in the heart of the sea. The enemy said, ‘I will pursue. I will overtake. I will divide the plunder. My desire will be satisfied on them. I will draw my sword. My hand will destroy them.’ You blew with your wind. The sea covered them. They sank like lead in the mighty waters. Who is like you, LORD, among the gods? Who is like you, glorious in holiness, fearful in praises, doing wonders? You stretched out your right hand. The earth swallowed them."

"Moses finished reciting all these words to all Israel. He said to them, “Set your heart to all the words which I testify to you today, which you shall command your children to observe to do, all the words of this law. For it is no vain thing for you, because it is your life, and through this thing you shall prolong your days in the land, where you go over the Jordan to possess it.” The LORD spoke to Moses that same day, saying, “Go up into this mountain of Abarim, to Mount Nebo, which is in the land of Moab, that is across from Jericho; and see the land of Canaan, which I give to the children of Israel for a possession. Die on the mountain where you go up, and be gathered to your people, as Aaron your brother died on Mount Hor, and was gathered to his people; because you trespassed against me among the children of Israel at the waters of Meribah of Kadesh, in the wilderness of Zin; because you didn’t uphold my holiness among the children of Israel. For you shall see the land from a distance; but you shall not go there into the land which I give the children of Israel.”"

"Kore the son of Imnah the Levite, the gatekeeper at the east gate, was over the free will offerings of God, to distribute the LORD’s offerings and the most holy things. Under him were Eden, Miniamin, Jeshua, Shemaiah, Amariah, and Shecaniah, in the cities of the priests, in their office of trust, to give to their brothers by divisions, to the great as well as to the small; in addition to those who were listed by genealogy of males, from three years old and upward, even everyone who entered into the LORD’s house, as the duty of every day required, for their service in their offices according to their divisions; and those who were listed by genealogy of the priests by their fathers’ houses, and the Levites from twenty years old and upward, in their offices by their divisions; and those who were listed by genealogy of all their little ones, their wives, their sons, and their daughters, through all the congregation; for in their office of trust they sanctified themselves in holiness. Also for the sons of Aaron the priests, who were in the fields of the pasture lands of their cities, in every city, there were men who were mentioned by name to give portions to all the males among the priests and to all who were listed by genealogy among the Levites. Hezekiah did so throughout all Judah; and he did that which was good, right, and faithful before the LORD his God."

"then I will punish their sin with the rod, and their iniquity with stripes. But I will not completely take my loving kindness from him, nor allow my faithfulness to fail. I will not break my covenant, nor alter what my lips have uttered. Once I have sworn by my holiness, I will not lie to David. His offspring will endure forever, his throne like the sun before me. It will be established forever like the moon, the faithful witness in the sky.” Selah. But you have rejected and spurned. You have been angry with your anointed. You have renounced the covenant of your servant. You have defiled his crown in the dust. You have broken down all his hedges. You have brought his strongholds to ruin. All who pass by the way rob him. He has become a reproach to his neighbors. You have exalted the right hand of his adversaries. You have made all of his enemies rejoice. Yes, you turn back the edge of his sword, and haven’t supported him in battle. You have ended his splendor, and thrown his throne down to the ground. You have shortened the days of his youth. You have covered him with shame. Selah. How long, LORD? Will you hide yourself forever? Will your wrath burn like fire? Remember how short my time is, for what vanity you have created all the children of men! What man is he who shall live and not see death, who shall deliver his soul from the power of Sheol? Selah."

"The LORD reigns! He is clothed with majesty! The LORD is armed with strength. The world also is established. It can’t be moved. Your throne is established from long ago. You are from everlasting. The floods have lifted up, LORD, the floods have lifted up their voice. The floods lift up their waves. Above the voices of many waters, the mighty breakers of the sea, the LORD on high is mighty. Your statutes stand firm. Holiness adorns your house, LORD, forever more."
