Matthew Henry's Complete Bible Commentary

Verse 13

Note, 1. Those that have no love for their business will never want excuses to shake it off. Multitudes are ruined, both for soul and body, by their slothfulness, and yet still they have something or other to say for themselves, so ingenious are men in putting a cheat upon their own souls. And who, I pray, will be the gainer at last, when the pretences will be all rejected as vain and frivolous? 2. Many frighten themselves from real duties by imaginary difficulties: The slothful man has work to do without in the fields, but he fancies there is a lion there; nay, he pretends he dares not go along the streets for fear somebody or other should meet him and kill him. He does not himself think so; he only says so to those that call him up. He talks of a lion without, but considers not his real danger from the devil, that roaring lion, which is in bed with him, and from his own slothfulness, which kills him. MHBCC 651.13
