'Whose' in the Bible

What then is Apollos? And what is Paul? They are just God's servants, through whose efforts, and as the Lord granted power to each, you accepted the faith.

Though I am not conscious of having been in any way unfaithful, yet I do not for that reason stand acquitted; but He whose scrutiny I must undergo is the Lord.

yet *we* have but one God, the Father, who is the source of all things and for whose service we exist, and but one Lord, Jesus Christ, through whom we and all things exist.
