Best defense for smiter?

Hi, I'm a mo/me smiter/healer and I usually bring only two defensive spells in 4v4. Currently I'm using divine boon with orison.
My question is: are there better dual defensive spells that I can use?

Here are some of the combos that I thought of:

Watchful spirit + contemplation of purity

mending + breeze

divine intervention + anything

live vicariously + balthazar's spirit

Any suggestions?
