If you are referring to the United Kingdom of Israel, the capital was initially Hebron, where Saul ruled and where David began his reign. David then conquered Jerusalem and established it as his capital and it continued to serve during Solomon's reign and it remained the capital of Judah until its defeat by Babylon. If the "Old Kingdom" refers to the Northern Kingdom of Israel, the capital was Samaria. If the "Old Kingdom" refers to the Old Kingdom Period in Egyptian History, there was no Israelite Kingdom during that time period as the Old Kingdom precedes the Biblical Arrival of the Israelites by nearly 1000 years.
At present it is Cairo. During the Old Kingdom the capital city was Memphis, during the Middle Kingdom and the New Kingdom it was Thebes.
The capital of ancient Egypt was first Memphis (during the Old Kingdom), then Thebes (during the Middle and the New Kingdom) until Alexander the Great invaded Egypt. He made Alexandria the capital and it remained Alexandria until the 7th cenutry.
