In hearing the Lord last November, as published in her urgent submission about Trump taking the Oath of Office, Veronika West writes of her reaction to its enormity:

‘As I listened, I began to pray fervently in The Spirit, and the burden of The LORD only increased as I saw a great War over The Oval and Oath of Office.
Satan knows that as soon as President Trump lays his right hand upon The Bible, the gavel will fall and a sudden mega-shift and a supernatural lifting and tipping of The Scales of Justice and Judgement will take place over The Nation!

Now, with these things still swirling in my heart after my prayer time, I went out to meet with some leaders in the afternoon, and not long into our conversation, one of the leaders said to me, ”Let’s pray for protection over Trump taking The Oath of Office — because that’s where the battle is!”

Veronika assumed Trump would follow the customary practice of placing a hand upon the Bible, but that didn’t happen much to the dismayed concern of some Christians and to many anti-Trumpers’ great delight!

I noticed during the Inauguration that it took a few seconds for the children alongside VP Vance taking the Oath of Office to move aside and thus enable First Lady to move forward, but Chief Justice John Roberts eagerly got into his role and started too soon.

EXPLANATIONS:

1. CBS News: Trump didn’t put his hand on the Bible at Inauguration – Here’s What To Know About The Tradition (emphasis mine)

‘While it is common for incoming presidents to place their hand on a Bible while taking the oath of office, it’s not a legal requirement.

Article VI of the U.S. Constitution states that “all executive and judicial Officers, both of the United States and of the several States, shall be bound by Oath or Affirmation, to support this Constitution; but no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States.”

First lady Melania Trump held two Bibles — one given to Mr. Trump by his mother when he was a child, and the Lincoln Bible, which was used at Abraham Lincoln’s 1861 inauguration. ‘

2. An answer citing unknown source:

3. My reaction; perhaps it’s an ‘optic’? (US slang: public understanding of a situation after seeing it shown in the media, and its possible political effects):

Upon reading the above I thought possibly not putting hand upon Bible may be another strong ‘optic’ – in 2017 Trump swore the Oath and in continuation as ‘wartime president’ during Biden’s ‘term’ he’s still in office and doesn’t need to repeat touching on the Bible.

4. Others:

‘Naughty!’ – ??

CONCLUSION:

Apparently it is not necessary to make the Oath with hand once again on a Bible after having done so previously.

Also, as well-informed observers know, Trump declared he’s a “wartime” president” and thereby the C-in-C during a military operation. Hence, when Biden flew in the USA his planes never carried the SAM (Special Air Mission) callsign or were covered by official no-fly exclusion zone – and his ‘inauguration’ did NOT have proper military canon salute.
