Pro 27:1 Boast not thyself of to morrow; for thou knowest not what a day may bring forth.
Pro 27:2 Let another man praise thee, and not thine own mouth; a stranger, and not thine own lips.
Pro 27:3 A stone is heavy, and the sand weighty; but a fool's wrath is heavier than them both.
Pro 27:4 Wrath is cruel, and anger is outrageous; but who is able to stand before envy?
Pro 27:5 Open rebuke is better than secret love.
Pro 27:6 Faithful are the wounds of a friend; but the kisses of an enemy are deceitful.
These are some good ones! Really, we do need to remember that first one. We can't brag about tomorrow as we're not sure what might happen. Only God knows.
And the second one is hard to hold in my head and heart sometimes as well. Much better to receive praise from someone else.
That last one can be hard to remember, and to take. It is much harder to accept correction from a friend than friendliness from an enemy, but it is for our own good. We should appreciate our friends when they care enough to correct us.
