Deuteronomy 13:3–4

²And thou shalt remember all the way which the Lord thy God led thee these forty years in the wilderness, to humble thee, and to prove thee, to know what was in thine heart, whether thou wouldest keep his commandments, or no.

¹⁹For there must be also heresies among you, that they which are approved may be made manifest among you.

¹⁰For thou, O God, hast proved us: thou hast tried us, as silver is tried.

¹BELOVED, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.

⁵And thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might.

¹¹And for this cause God shall send them strong delusion, that they should believe a lie:

²⁰To the law and to the testimony: if they speak not according to this word, it is because there is no light in them.

²⁴For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.

¹⁴And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live.

¹⁹They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us.

⁴Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world.

⁸I speak not by commandment, but by occasion of the forwardness of others, and to prove the sincerity of your love.

¹¹These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.

¹⁶Who fed thee in the wilderness with manna, which thy fathers knew not, that he might humble thee, and that he might prove thee, to do thee good at thy latter end;

¹⁴That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive;

⁷Thou calledst in trouble, and I delivered thee; I answered thee in the secret place of thunder: I proved thee at the waters of Meribah. Selah.

¹⁰That ye might walk worthy of the Lord unto all pleasing, being fruitful in every good work, and increasing in the knowledge of God;

²⁰Thou shalt fear the Lord thy God; him shalt thou serve, and to him shalt thou cleave, and swear by his name.

¹⁷But he that is joined unto the Lord is one spirit.

²³But this thing commanded I them, saying, Obey my voice, and I will be your God, and ye shall be my people: and walk ye in all the ways that I have commanded you, that it may be well unto you.

³¹And the king stood in his place, and made a covenant before the Lord, to walk after the Lord, and to keep his commandments, and his testimonies, and his statutes, with all his heart, and with all his soul, to perform the words of the covenant which are written in this book.

³¶ And the king stood by a pillar, and made a covenant before the Lord, to walk after the Lord, and to keep his commandments and his testimonies and his statutes with all their heart and all their soul, to perform the words of this covenant that were written in this book. And all the people stood to the covenant.

²⁰That thou mayest love the Lord thy God, and that thou mayest obey his voice, and that thou mayest cleave unto him: for he is thy life, and the length of thy days: that thou mayest dwell in the land which the Lord sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give them.

⁸He hath shewed thee, O man, what is good; and what doth the Lord require of thee, but to do justly, and to love mercy, and to walk humbly with thy God?

¹FURTHERMORE then we beseech you, brethren, and exhort you by the Lord Jesus, that as ye have received of us how ye ought to walk and to please God, so ye would abound more and more.

²For ye know what commandments we gave you by the Lord Jesus.

¹³Thou shalt fear the Lord thy God, and serve him, and shalt swear by his name.

⁶And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless.

¹³Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God.
