Calving trouble is composed of Ark a photograph of Swan Vesta matchboxes digitally altered to show, not one but two swans on the lids, representing the two cherubim on the Ark of the Covenant; 2 digitally handwritten texts in English and German also tell the imagined story of the biblical Uri ben Hur, father of the artist Bezalel and son of Hur whom the Israelites murdered when, in the name of a monotheist God, he protested against their worshipping of the golden calf. In this tale at the birth of a nation, Tanya Ury's character Uri ben Hur suspects that his son may have assisted Aaron, Moses' brother, in the creation of the golden calf idol. Uri also points out the inconsistencies in Moses' Law when promoting the case for murder and acquisition of another's property in the conquest of the Promised Land. He relates how the Israelites often complained of their nomad existence with all its risks; even if their goal was a land of milk and honey, they would have preferred to return to bondage in Egypt where they had been at home for generations.

For the DVD version of Promised Land, several series of photographs taken with a drive camera function are displayed within the space of a few seconds showing photographic images of Bezalel lighting matches from a Swan Vesta matchbox, that present the Ark of the Covenant, as a Pandora's tinderbox.

Calving trouble will eventually be composed of one or more bull calf statuettes of bronze (size undecided).
