'Thread' in the Bible

that I will not take a thread nor a sandal strap nor anything that is yours, lest you should say, 'I have made Abram rich.'

When she travailed, one put out a hand, and the midwife took and tied a scarlet thread on his hand, saying, "This came out first."

Afterward his brother came out, that had the scarlet thread on his hand, and his name was called Zerah.
