Numbers 30:2 When one of you men makes a promise to the Lord, you must keep your word.
Some verses really don’t need much deeper study or explanation. There’s no hidden meaning buried somewhere in the original Hebrew. It’s a very plain command, not a polite suggestion: I must keep my promises to You.
I like to think I’m a man of my word but there are many times I’ve made some bold statement of what I’m going to do for You, then promptly forgot it. I sometimes use my words too lightly.
Lord, remind me of the things I’ve already promised to You that I need to do right away. From now on give me an open heart and a guarded tongue.
