Proverbs 15:19

19 The way of the slothful is as hedged with thorns; But the path of the righteous is paved. Hitzig misses the contrast between אצל (slothful) and ישׁרים (upright), and instead of the slothful reads עריץ, the tyrannical. But is then the slothful ישׁר? The contrast is indeed not that of contradiction, but the slothful is one who does not act uprightly, a man who fails to fulfil the duty of labour common to man, and of his own special calling. The way of such an one is כּמשׂכת חדק, like a fencing with thorns (from חדק, R. חד, to be pointed, sharp, distinguished from Arab. hadḳ, to surround, and in the meaning to fix with the look, denom. of khadaḳt, the apple of the eye), so that he goes not forwards, and sees hindrances and difficulties everywhere, which frighten him back, excusing his shunning his work, his remissness of will, and his doing nothing; on the contrary, the path of those who wait truly and honestly on their calling, and prosecute their aim, is raised up like a skilfully made street, so that unhindered and quickly they go forward (סלוּלה, R. סל, aggerare, cf. Jer 18:15 with Isa 49:11 and Isa 49:4 :8, סלסל, which was still in use in the common language of Palestine in the second cent., Rosch haschana, 26b).

See here, 1. Whence those difficulties arise which men pretend to meet with in the way of their duty, and to be insuperable; they arise not from any thing in the nature of the duty, but from the slothfulness of those that have really no mind to it. Those that have no heart to their work pretend that their way is hedged up with thorns, and they cannot do their work at all (as if God were a hard Master, reaping where he had not sown), at least that their way is strewed with thorns, that they cannot do their work without a great deal of hardship and danger; and therefore they go about it with as much reluctance as if they were to go barefoot through a thorny hedge. 2. How these imaginary difficulties may be conquered. An honest desire and endeavour to do our duty will, by the grace of God, make it easy, and we shall find it strewed with roses: The way of the righteous is made plain; it is easy to be trodden and not rough, easy to be found, and not intricate.

15:19 A lazy person can find all kinds of obstacles (e.g., a path blocked with briers) to avoid work (see 10:4, 26; 12:11, 14; 13:4; 14:4).
