Gregory the Great, on Prov 20:4

“Because of the cold the sluggard would not plough: he shall beg therefore in the summer, and it shall not be given him.”

“For the most part the slothful, while he neglects to do things that are necessary, sets before him some that are difficult, but is inconsiderately afraid of others; and so, as though finding something that he may reasonably fear, he satisfies himself that he has good reason for remaining torpid. To him it is rightly said through Solomon, "The sluggard would not plough by reason of the cold; therefore shall he beg in summer, and it shall not be given unto him." For indeed the sluggard ploughs not by reason of the cold, when he finds an excuse for not doing the good things which he ought to do. The sluggard ploughs not by reason of the cold, when he is afraid of small evils that are against him, and leaves undone things of the greatest importance. Further it is well said, "He shall beg in summer, and it shall not be given unto him." For whoso toils not now in good works will beg in summer and receive nothing, because, when the burning sun of judgment shall appear, he will then sue in vain for entrance into the kingdom.”
