'Consider your ways' means the people should look honestly at the results of their choices and priorities. In Haggai 1, they have built their own houses while the LORD's house remains neglected.
Haggai speaks to returned exiles who are living in the land but delaying the temple work. Their frustration with crops and wages becomes a summons to examine what they are seeking first. The command is practical, covenantal, and public.
The phrase helps readers see that biblical repentance is not vague self-improvement. It means bringing real priorities under God's word.
5Now therefore this is what Yahweh of Hosts says: Consider your ways.
