'Pledging' in the Bible

Today you have [openly] declared the Lord to be your God, and that you will walk [that is, live each and every day] in His ways and keep His statutes, His commandments, and His judgments (precepts), and listen to His voice.

And there are who are saying, 'Our fields, and our vineyards, and our houses, we are pledging, and we receive corn for the famine.'
