Answer 1

210 are the years of shi'bud Mitzrayim. (Rash"i on B'reshis 15:13)

Answer 2

Iyov lived 210 years - seventy before his troubles, and 140 after them. (Bava Basra 15b, top, and Rashi there ד"ה אימא)

Answer 3

Parshas Mikeitz (Braishis 42:2) Yaakov sends his sons to Mitzrayim saying, “רְדוּ שָׁמָּה” “go down to there.” Rashi points out that Yaakov specifically said "רְדוּ", “descend”, and not "לְכוּ", “go”, because 210 = רְדוּ to show that they will remain there for 210 years.

Answer 4

210 is the total number of days in all the Adar Rishon months in a nineteen-year cycle.
