Haggai 1:5

“Now therefore thus saith the Lord of hosts, etc.] The Lord God omniscient and omnipotent, that saw all their actions, and could punish for them; since they were so careful of their own houses, and adorning them, and so careless of his house; he would have them now sit down, and seriously think of these things, and of what he should further observe unto them: Consider your ways; their sinful ways, and repent of them, and forsake them, particularly their ingratitude before observed; and their civil ways, their common ways of life; their labour, work, and business, they were continually employed in; and observe the event of them; what success they had, what these issued in; whether there were…”

“Consider your ways--literally, "Set your heart" on your ways. The plural implies, Consider both what ye have done (actively, Lam 3:40) and what ye have suffered (passively) [JEROME]. Ponder earnestly whether ye have gained by seeking self at the sacrifice of God.”

“And now, thus saith the Lord of hosts; “Consider,” (literally “set your heart upon) your ways,” what they had been doing, what they were doing, and what those doings had led to, and would lead to. This is ever present to the mind of the prophets, as speaking God’s words, that our acts are not only “ways” in which we go, each day of life being a continuance of the day before; but that they are ways which lead, somewhere in God’s Providence and His justice; to some end of the “way,” good or bad. So God says by Jeremiah Jeremiah 21:8. “I set before you the way of life and the way of death;” and David Psalms 16:11, “Thou wilt show me the path of life,” where it follows, “In Thy presence is the…”

“1:5 Look at what’s happening to you (literally Set your heart on these matters): For the Hebrews, the heart is the place where thinking, feeling, and willing all occur. So this command (also 1:7; 2:15, 18) calls upon the people to think carefully and draw the proper conclusions about the connection between what’s happening to them (drought and poverty, 1:6) and their failure to restore proper worship of the Lord (1:8-9).”

“thus: Hag 1:7, Hag 2:15-18; Lam 3:40; Eze 18:28; Luk 15:17; Co2 13:5; Gal 6:4 Consider your ways: Heb. Set your heart on your ways, Exo 7:23, Exo 9:21 \*marg. Psa 48:13 \*marg. Eze 40:4; Dan 6:14, Dan 10:12 Haggai 1:6”

“After rebutting the untenable grounds of excuse, Haggai calls attention in vv. 5, 6 to the curse with which God has punished, and is still punishing, the neglect of His house. Hag 1:5. "And now, thus saith Jehovah of hosts, Set your heart upon your ways. Hag 1:6. Ye have sowed much, and brought in little: ye eat, and not for satisfaction; drink, and not to be filled with drink: ye clothe yourselves, and it does not serve for warming; and the labourer for wages works for wages into a purse pierced with holes." שׂימוּ לבבכם, a favourite formula with Haggai (cf. v. 7 and Hag 2:15, Hag 2:18). To set the heart upon one's ways, i.e., to consider one's conduct, and lay it to heart. The ways are the…”
