“Blessed are all who fear Yahweh, who walk in his ways”
The Old Testament has a pretty long list of instructions on how to live well. While many are about relating well to God, most are about how to care for each other, and how to create a society where people thrive. It includes many instructions about caring for the poor and vulnerable, preventing homelessness, looking after refugees and immigrants, food security, respect for property, and making restitution.
When people lived by those rules, it meant they treated each other with dignity and respect. A broad commitment to ethical behaviour meant things went well in their society, and in Psalm 128 that’s particularly reflected in the family.
