Why were things like the olive branch and the dove chosen?

The olive branch and the dove have long been symbols of peace and reconciliation. The olive branch, rooted in ancient cultures, represents prosperity and hope, often associated with the idea of a truce or an end to conflict. The dove, particularly in the biblical context, signifies purity and the Holy Spirit, famously representing peace when it returned to Noah's Ark with an olive leaf. Together, they convey a universal message of harmony and the restoration of relationships.
