Use "obsecration" in a sentence
"Thine own sake, O my God_; [256] to this belongs _obsecration_ -- namely, an appeal to sacred things, as when we say: _By Thy Nativity, deliver us, O Lord_!"
"But it is sufficient to remark that _obsecration_ is not a swearing by, or adjuring of God, as though to compel Him, for this is forbidden, but to implore His mercy."
"And _obsecration_ precedes _prayer_, for it is from dwelling upon the Divine"
