“Veneration of relics, of all things, is entirely biblical.
even there were brought from his body to the sick, handkerchiefs and aprons, and the diseases departed from them, and the wicked spirits went out of them. (Acts 19:12)”
The desire and practice was a desire to be healed because of contact with the items. They did not pray to them, kiss them, worship them, venerate them. Never recorded.
They collected them and believed in the healing power of relics. That is veneration. Entirely biblical.
