Final answer:
When feeling festive, the Hebrews likely wore garments of purple and gold, as these colors were historically associated with royalty, wealth, and celebration. Option 3.
Step-by-step explanation:
Color choices for clothing and celebration in historical contexts often had specific cultural meanings.
In the case of the Hebrews, while not explicitly stated in the provided references, it can be understood from historical and biblical contexts that purple and gold were colors associated with royalty and wealth, which could signify festivity and celebration. Purple was extracted from the rare Murex shellfish, which made it costly and thus a status symbol.
Similarly, gold has universally been seen as a precious and festive color.
While wearing simple white garments was often related to purity and joyful occasions among various historical traditions, including the Hebrews, for a festive occasion, more illustrious colors such as purple and gold, which convey a sense of celebration and wealth, would likely have been preferred.
Therefore, based on the context, when the Hebrews were feeling festive, they would likely wear garments of purple and gold (option 3).
