Right or community of blood was not the bond of union between them, so much as interest or compulsion as the case may be. Thucydides
The principle of subordination is the great bond of union and harmony through the universe. Catharine Beecher
Law is the gift of God, the model of equity, a standard of justice, a likeness of the divine will, the guardian of well-being, a bond of union and solidarity between peoples, a rule defining duties, a barrier against the vices and the destroyer thereof, a punishment of violence and all wrongdoing. John of Salisbury
