1st Samuel 16:6

3 And call Jesse to the sacrifice, and I will shew thee what thou shalt do: and thou shalt anoint unto me him whom I name unto thee.

4 And Samuel did that which the LORD spake, and came to Bethlehem. And the elders of the town trembled at his coming, and said, Comest thou peaceably?

5 And he said, Peaceably: I am come to sacrifice unto the LORD: sanctify yourselves, and come with me to the sacrifice. And he sanctified Jesse and his sons, and called them to the sacrifice.

6 And it came to pass, when they were come, that he looked on Eliab, and said, Surely the LORD'S anointed is before him.

7 But the LORD said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for the LORD seeth not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart.

8 Then Jesse called Abinadab, and made him pass before Samuel. And he said, Neither hath the LORD chosen this.

9 Then Jesse made Shammah to pass by. And he said, Neither hath the LORD chosen this.
