'Undivided' in the Bible

"Remember me, LORD," he said, "how I have walked in your presence with integrity, with an undivided heart, and I have accomplished what is good in your sight." And Hezekiah wept deeply.

The tribe of Zebulun supplied 50,000 experienced troops, trained in the use of every kind of war weapon, in order to help David with undivided loyalty.

Teach me Your way, Yahweh,and I will live by Your truth.Give me an undivided mind to fear Your name.
