Isaiah 17:10 warns Israel for forgetting God, the source of their salvation and strength. It highlights that, due to neglecting their relationship with God, they will try to find security and prosperity through foreign alliances and idolatry, symbolized by planting “pleasant plants” and setting “strange slips.” This serves as a warning that relying on anything other than God will lead to failure and disappointment, stressing the importance of trusting in God’s unwavering power and protection.

Because thou hast forgotten the God of thy salvation, and hast not been mindful of the rock of thy strength, therefore shalt thou plant pleasant plants, and shalt set it with strange slips: Isaiah 17:10 KJV

Why Bridges Don’t Sink (practical.engineering) The essence of a bridge is not just that it goes over something, but that there’s clear space underneath for a river, railway, or road. Maybe this is already obvious to you, but bridges present a unique structural challenge. In a regular road, the forces are transferred directly into the ground. On a bridge, all those forces on the span get concentrated into the piers or abutments on either side. Because of that, bridge substructures are among the strongest engineered systems on the planet. And yet, bridge foundations are built in some of the least ideal places for heavy loading. Rivers and oceans have soft, mucky soils that can’t hold much weight. Plus, obviously, a lot of them are underwater.
