Catena Aurea on Matthew 13:18–23: Jerome

For the joining together of the hands, as it were in the soft embrace of a kiss, represents husband and wife. The sixty-fold refers to widows, who as being set in narrow circumstances and affliction are denoted by the depression of the finger; for by how much greater is the difficulty of abstaining from the allurements of pleasure once known, so much greater is the reward. The hundredth number passes from the left to the right, and by its turning round with the same fingers, not on the same hand, it expresses the crown of virginity. [ed. note: ~ This alludes to the method of notation by the fingers described by Bede (with reference to this passage of S. Jerome,) in his treatise ‘De Indigitatione,’ vol i. 131. The expression, ‘atque suos jam dextra computat annos,’ Juv. will occur immediately to the classical reader.]
