Luke 16:17

μίαν κεραίαν. The tip or horn of a letter, such as that which distinguishes ב from כ or ה from ח. Thus the Jews said that the letter Yod prostrated itself before God, because Solomon had taken it from the law (in the word Nashim) by marrying many wives, and God made this same answer to them. Similarly they said that when God took the Yod (the “jot” of Matthew 5:18) from the name Sarai, He divided it between Sarah and Abraham, since Yod = 10, and H = 5.

πεσεῖν. ‘To fall.’ See Matthew 5:18. The law did not fall to the ground; its abrogation was only its absolute fulfilment in all its eternal principles. The best comment on the verse is Matthew 5:27-48. The bearing of these remarks on the previous ones seems to be that our Lord charges the Pharisees with hypocrisy and men-pleasing, because while they professed the most scrupulous reverence to the Law, they lived in absolute violation of its spirit, which was alone valuable in God’s sight.
