'Knots' in the Bible

because that an excellent spirit, and knowledge, and understanding, interpreting of dreams, and showing of enigmas, and loosing of knots was found in him, in Daniel, whose name the king made Belteshazzar: now let Daniel be called, and the interpretation he doth show.'

and I -- I have heard of thee, that thou art able to give interpretations, and to loose knots: now, lo -- thou art able to read the writing, and its interpretation to cause me to know -- purple thou dost put on, and a bracelet of gold is on thy neck, and third in the kingdom thou dost rule.'
