正确的句子应该是
to have and to hold them from this day forward
其中from this day forward 是从今以后的意思
to have and to hold是享有,永远保有的意思
例句
I bequeath him this property to have and to hold.
我将此项财产遗赠给他,归他永久享有.
To have and to hold from this day forward,for better or worse,richness or poverty,sickness or health,to love and to cherish,till death do us part.
从这一天起,无论境遇好坏,无论贫穷富有,无论生病还是健康,我们将始终相亲相爱,至死不渝.
