'Knots' in the Bible

(Resh) Look, O Lord! I am distressed; my stomach is in knots! My heart is pounding inside me. Yes, I was terribly rebellious! Out in the street the sword bereaves a mother of her children; Inside the house death is present.

(Kaf) My eyes are worn out from weeping; my stomach is in knots. My heart is poured out on the ground due to the destruction of my helpless people; children and infants faint in the town squares.

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.'
