Bibli-questions

Am I my brother's keeper
When he's lying in the field?
Though my hands are clean, now,
Still with blood they're stained

Do I defend my sister's virtue
Even in the marriage bed?
When all is said and done
And the sheets are turning red-

Must I console my son
When he's ripe for sacrifice-
Bound upon the altar
Under a cruel and hungry knife?

Dare I keep my father's vigil
When he's nailed upon the cross-
Dying for the damned
And shepherding the lost?

Do I question G-d Almighty
About his master plan?
Or just do as I am told
Head buried in the sand?
