Keeping silent in the days of Evil

Ephesians Chapter 5: 14 Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light.
15 See then that ye walk circumspectly, not as fools, but as wise,
16 Redeeming the time, because the days are evil.

Amos Chapter 5: 11 Forasmuch therefore as your treading [is] upon the poor, and ye take from him burdens of wheat: ye have built houses of hewn stone, but ye shall not dwell in them; ye have planted pleasant vineyards, but ye shall not drink wine of them.
12 For I know your manifold transgressions and your mighty sins: they afflict the just, they take a bribe, and they turn aside the poor in the gate [from their right].
13 Therefore the prudent shall keep silence in that time; for it [is] an evil time.
14 Seek good, and not evil, that ye may live: and so the LORD, the God of hosts, shall be with you, as ye have spoken.
17 Wherefore be ye not unwise, but understanding what the will of the Lord [is].
