In the old English sense, means alive, or living. Nu 16:30; 2Ti 4:1; and quicken, to make alive. God bestows spiritual life on men dead in trespasses and sins, Eph 2:5, through Christ the second Adam, who is a quickening Spirit, 1Co 15:45.
But if the LORD make a new thing, and the earth open her mouth, and swallow them up, with all that appertain unto them, and they go down quick into the pit; then ye shall understand that these men have provoked the LORD.
And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit.
Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)
