Proverbs 6:6-11 (ESV) –
6 Go to the ant, O sluggard;
    consider her ways, and be wise.
7 Without having any chief,
    officer, or ruler,
8 she prepares her bread in summer
    and gathers her food in harvest.
9 How long will you lie there, O sluggard?
    When will you arise from your sleep?
10 A little sleep, a little slumber,
    a little folding of the hands to rest,
11 and poverty will come upon you like a robber,
    and want like an armed man.

Proverbs 10:4-5 (ESV) –
4 A slack hand causes poverty,
    but the hand of the diligent makes rich.
5 He who gathers in summer is a prudent son,
    but he who sleeps in harvest is a son who brings shame.

Luke 21:34-36 (ESV) –
34 “But watch yourselves lest your hearts be weighed down with dissipation and drunkenness and cares of this life, and that day come upon you suddenly like a trap. 35 For it will come upon all who dwell on the face of the whole earth. 36 But stay awake at all times, praying that you may have strength to escape all these things that are going to take place, and to stand before the Son of Man.”

1 Thessalonians 5:6

(ESV) 6 So then let us not sleep, as others do, but let us keep awake and be sober.

(AMP) 6 So then let us not sleep [in spiritual indifference] as the rest [of the world does], but let us keep wide awake [alert and cautious] and let us be sober [self-controlled, calm, and wise].

Mark 13:32-37 (ESV) –
32 “But concerning that day or that hour, no one knows, not even the angels in heaven, nor the Son, but only the Father. 33 Be on guard, keep awake. For you do not know when the time will come. 34 It is like a man going on a journey, when he leaves home and puts his servants in charge, each with his work, and commands the doorkeeper to stay awake. 35 Therefore stay awake—for you do not know when the master of the house will come, in the evening, or at midnight, or when the rooster crows, or in the morning— 36 lest he come suddenly and find you asleep. 37 And what I say to you I say to all: Stay awake.”
