'Thread' in the Bible

that I will not take a thread nor a shoe-latchet nor aught that is thine, lest thou shouldest say, I have made Abram rich:

And it came to pass, when she travailed, that one put out a hand: and the midwife took and bound upon his hand a scarlet thread, saying, This came out first.

And afterward came out his brother, that had the scarlet thread upon his hand: and his name was called Zerah.

Behold, when we come into the land, thou shalt bind this line of scarlet thread in the window which thou didst let us down by: and thou shalt gather unto thee into the house thy father, and thy mother, and thy brethren, and all thy father's household.

So Delilah took new ropes, and bound him therewith, and said unto him, The Philistines are upon thee, Samson. And the liers-in-wait were abiding in the inner chamber. And he brake them off his arms like a thread.

Thy lips are like a thread of scarlet, And thy mouth is comely. Thy temples are like a piece of a pomegranate Behind thy veil.
