'Thread' in the Bible

that I would not take anything that is yours, from a thread to a sandal strap, so you could not say, ‘I [the King of Sodom] have made Abram rich.’

And when she was in labor, one [baby] put out his hand, and the midwife took his hand and tied a scarlet thread on it, saying, “This one was born first.”

Afterward his brother who had the scarlet [thread] on his hand was born and was named Zerah (brightness).
