But cursed be he that dealeth craftily, Whereas he hath in his flock a male, And voweth, and sacrificeth unto the Lord a blemished thing; For I am a great King, Saith the LORD of hosts, And My name is feared among the nations.
Rashi on Malachi
he who deals craftily Plots deceitfully, with guile, before Me, saying, “I have none better than this.”
Rashi on Malachi
and he vows and sacrifices a blemished one as in (Lev. 22:25), “their corruption is in them; a blemish is in them.”
