Ye strike you is the same.
They strike them is ambiguous.
This shows the value of a reflective pronoun for the third person.
As a general rule, therefore, whenever we use a verb reflectively we use the word self in combination with the personal pronoun.
Yet this was not always the case. The use of the simple personal pronoun was current in Anglo-Saxon, and that, not only for the first two persons, but for the third as well.
The exceptions to this rule are either poetical expressions, or imperative moods.
He sat him down at a pillar's base.—Byron.
Sit thee down.
[§ 442]. Reflective neuters.—In the phrase I strike me, the verb strike is transitive; in other words, the word me expresses the object of an action, and the meaning is different from the meaning of the simple expression I strike.
In the phrase I fear me (used by Lord Campbell in his lives of the Chancellors), the verb fear is intransitive or neuter; in other words, the word me (unless, indeed, fear mean terrify), expresses no object of any action at all; whilst the meaning is the same as in the simple expression I fear.
