time to kill - namely, judicially, criminals; or, in wars of self-defense; not in malice. Out of this time and order, killing is murder.
to heal - God has His times for “healing” (literally, Isa 38:5, Isa 38:21; figuratively, Deu 32:39; Hos 6:1; spiritually, Psa 147:3; Isa 57:19). To heal spiritually, before the sinner feels his wound, would be “out of time,” and so injurious.
time to break down - cities, as Jerusalem, by Nebuchadnezzar.
build up - as Jerusalem, in the time of Zerubbabel; spiritually (Amo 9:11), “the set time” (Psa 102:13-16).
