Pre-existence

Jeremiah 1:5

 5 Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the nations.

Proverbs 8:22-31

 22 The Lord possessed me in the beginning of his way, before his works of old.

 23 I was set up from everlasting, from the beginning, or ever the earth was.

 24 When there were no depths, I was brought forth; when there were no fountains abounding with water.

 25 Before the mountains were settled, before the hills was I brought forth:

 26 While as yet he had not made the earth, nor the fields, nor the highest part of the dust of the world.

 27 When he prepared the heavens, I was there: when he set a compass upon the face of the depth:

 28 When he established the clouds above: when he strengthened the fountains of the deep:

 29 When he gave to the sea his decree, that the waters should not pass his commandment: when he appointed the foundations of the earth:

 30 Then I was by him, as one brought up with him: and I was daily his delight, rejoicing always before him;

 31 Rejoicing in the habitable part of his earth; and my delights were with the sons of men.
