Tawhid in the Bible
Deuteronomy 6:4-15 KJV
6 Now these are the commandments, the statutes, and the judgments, which the Lordyour God commanded to teach you, that ye might do them in the land whither ye go to possess it:
2 That thou mightest fear the Lord thy God, to keep all his statutes and his commandments, which I command thee, thou, and thy son, and thy son's son, all the days of thy life; and that thy days may be prolonged.
3 Hear therefore, O Israel, and observe to do it; that it may be well with thee, and that ye may increase mightily, as the Lord God of thy fathers hath promised thee, in the land that floweth with milk and honey.
4 Hear, O Israel: The Lord our God is one Lord:
5 And thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might.
6 And these words, which I command thee this day, shall be in thine heart:
7 And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up.
8 And thou shalt bind them for a sign upon thine hand, and they shall be as frontlets between thine eyes.
9 And thou shalt write them upon the posts of thy house, and on thy gates.
10 And it shall be, when the Lord thy God shall have brought thee into the land which he sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give thee great and goodly cities, which thou buildedst not,
11 And houses full of all good things, which thou filledst not, and wells digged, which thou diggedst not, vineyards and olive trees, which thou plantedst not; when thou shalt have eaten and be full;
12 Then beware lest thou forget the Lord, which brought thee forth out of the land of Egypt, from the house of bondage.
13 Thou shalt fear the Lord thy God, and serve him, and shalt swear by his name.
14 Ye shall not go after other gods, of the gods of the people which are round about you;
15 (For the Lord thy God is a jealous God among you) lest the anger of the Lord thy God be kindled against thee, and destroy thee from off the face of the earth.
These verses clearly show the call to worship only one god, with out any partners and or associates in worship. So how can the trinity be explained?
Jesus answered him, “The first of all the commandments is: ‘Hear, O Israel, the LORD our God, the LORD is one.

The Greatest Commandment(A)
28 One of the teachers of the law came and heard them debating. Noticing that Jesus had given them a good answer, he asked him, “Of all the commandments, which is the most important?”
29 “The most important one,” answered Jesus, “is this: ‘Hear, O Israel: The Lord our God, the Lord is one.30 Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.’31 The second is this: ‘Love your neighbor as yourself.’There is no commandment greater than these.”
32 “Well said, teacher,” the man replied. “You are right in saying that God is one and there is no other but him. 33 To love him with all your heart, with all your understanding and with all your strength, and to love your neighbor as yourself is more important than all burnt offerings and sacrifices.”
34 When Jesus saw that he had answered wisely, he said to him, “You are not far from the kingdom of God.”And from then on no one dared ask him any more questions.
