'Injunctions' in the Bible

But He gave them strict injunctions not to blaze abroad His doings,

but He gave strict injunctions that the matter should not be made known, and directed them to give her something to eat.

Carry out these injunctions because you know the critical period at which we are living, and that it is now high time, to rouse yourselves from sleep; for salvation is now nearer to us than when we first became believers.

referring to things which are all intended to be used up and perish--in obedience to mere human injunctions and teachings?
