What are the "Sipim"?
1.
Targum Yonasan: They are Kuiya. Rashi - I am unsure if they are musical instruments, or buckets to receive blood, like "ha'Dam Asher ba'Saf" (Shemos 12:22). Some say that they are jugs, for so Onkelos translated "v'Chadah Al Shichmah" (Bereishis 24:15) v'Kulsah Al Kaspah. This seems correct.
2)
What are "Menakiyos"?
1.
Rashi (citing Menachos 96a): They are gold stands that hold up Lechem ha'Panim.
3)
What did Rav Tabachim do with everything in this verse?
1.
Malbim: He took them to the king's storehouse.
