If you have a desire to help, then give to the homeless, be it money or your time.

=

If you have a desire to help, then give to the homeless, whether it is (或be) money or your time.

If you have a desire to help, then give to the homeless, be it money or your time.

请问后面的划线部分是省略句吗? 感觉很奇怪

     【答】 be it money or your time 是一个以 be 开头的让步状语从句。例如：

       All magnets behave the same, whether they be large or small. =  All magnets behave the same, be they  large or small. 所有磁体，不论大小，性质相似。（摘自赵俊英：《现代英语语法》p.1379）

      所以，

      If you have a desire to help, then give to the homeless, be it money or your time.

     =If you have a desire to help, then give to the homeless, whether it be money or your time.

      whether ... or ... 的意思是“无论...... 还是...... ”、“不管...... 还是...... ”。
