2 Kings 4: 38 And Elisha came again to Gilgal: and there was a dearth in the land; and the sons of the prophets were sitting before him: and he said unto his servant, Set on the great pot, and seethe pottage for the sons of the prophets.39 And one went out into the field to gather herbs, and found a wild vine, and gathered thereof wild gourds his lap full, and came and shred them into the pot of pottage: for they knew them not. 40 So they poured out for the men to eat. And it came to pass, as they were eating of the pottage, that they cried out, and said, O thou man of God, there is death in the pot. And they could not eat thereof. 41 But he said, Then bring meal. And he cast it into the pot; and he said, Pour out for the people, that they may eat. And there was no harm in the pot.
Hebrews 5: 11 Of whom we have many things to say, and hard to be uttered, seeing ye are dull of hearing. 12 For when for the time ye ought to be teachers, ye have need that one teach you again which be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat. 13 For every one that useth milk is unskilful in the word of righteousness: for he is a babe. 14 But strong meat belongeth to them that are of full age, even those who by reason of use have their senses exercised to discern both good and evil.
1Thes. 5:21 Prove all things, hold fast that which is good.
1 Cor. 2: 12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God. 13 Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual. 14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned. 15 But he that is spiritual judgeth all things, yet he himself is judged of no man. 16 For who hath known the mind of the Lord, that he may instruct him? but we have the mind of Christ.
